I don't remember having see that behavior with these OSes but filenames with embedded spaces were rare at that time. Anyway, have you examples of currently used find implementations that exhibit this behavior (outside Dean's experience which is perplexing me) ?

I believe that would violate the POSIX standard if I understand it correctly:

Quoted from http://www.opengroup.org/onlinepubs/...ties/find.html
An argument containing only the two characters "{}" shall be replaced by the set of aggregated pathnames, with each pathname passed as a separate argument to the invoked utility in the same order that it was aggregated.

XARGS(1)						    BSD General Commands Manual 						  XARGS(1)

NAME
xargs -- construct argument list(s) and execute utility SYNOPSIS
xargs [-0pt] [-E eofstr] [-I replstr [-R replacements]] [-J replstr] [-L number] [-n number [-x]] [-s size] [utility [argument ...]] DESCRIPTION
The xargs utility reads space, tab, newline and end-of-file delimited arguments from the standard input and executes the specified utility with them as arguments. The utility and any arguments specified on the command line are given to the utility upon each invocation, followed by some number of the arguments read from standard input. The utility is repeatedly executed until standard input is exhausted. Spaces, tabs and newlines may be embedded in arguments using single (`` ' '') or double (``"'') quotes or backslashes (``''). Single quotes escape all non-single quote characters, excluding newlines, up to the matching single quote. Double quotes escape all non-double quote char- acters, excluding newlines, up to the matching double quote. Any single character, including newlines, may be escaped by a backslash. The options are as follows: -0 Change xargs to expect NUL (``'') characters as separators, instead of spaces and newlines. This is expected to be used in concert with the -print0 function in find(1). -E eofstr Use eofstr as a logical EOF marker. -I replstr Execute utility for each input line, replacing one or more occurences of replstr in up to replacements (or 5 if no -R flag is speci- fied) arguments to utility with the entire line of input. The resulting arguments, after replacement is done, will not be allowed to grow beyond 255 bytes; this is implemented by concatenating as much of the argument containing replstr as possible, to the con- structed arguments to utility, up to 255 bytes. The 255 byte limit does not apply to arguments to utility which do not contain replstr, and furthermore, no replacement will be done on utility itself. Implies -x. -J replstr If this option is specified, xargs will use the data read from standard input to replace the first occurrence of replstr instead of appending that data after all other arguments. This option will not effect how many arguments will be read from input (-n), or the size of the command(s) xargs will generate (-s). The option just moves where those arguments will be placed in the command(s) that are executed. The replstr must show up as a distinct argument to xargs. It will not be recognized if, for instance, it is in the middle of a quoted string. Furthermore, only the first occurrence of the replstr will be replaced. For example, the following com- mand will copy the list of files and directories which start with an uppercase letter in the current directory to destdir: /bin/ls -1d [A-Z]* | xargs -J % cp -rp % destdir -L number Call utility for every number lines read. If EOF is reached and fewer lines have been read than number then utility will be called with the available lines. -n number Set the maximum number of arguments taken from standard input for each invocation of the utility. An invocation of utility will use less than number standard input arguments if the number of bytes accumulated (see the -s option) exceeds the specified size or there are fewer than number arguments remaining for the last invocation of utility. The current default value for number is 5000. -p Echo each command to be executed and ask the user whether it should be executed. An affirmative response, 'y' in the POSIX locale, causes the command to be executed, any other response causes it to be skipped. No commands are executed if the process is not attached to a terminal. -R replacements Specify the maximum number of arguments that -I will do replacement in. -s size Set the maximum number of bytes for the command line length provided to utility. The sum of the length of the utility name, the arguments passed to utility (including NULL terminators) and the current environment will be less than or equal to this number. The current default value for size is ARG_MAX - 4096. -t Echo the command to be executed to standard error immediately before it is executed. -x Force xargs to terminate immediately if a command line containing number arguments will not fit in the specified (or default) command line length. If no utility is specified, echo(1) is used. Undefined behavior may occur if utility reads from the standard input. The xargs utility exits immediately (without processing any further input) if a command line cannot be assembled, utility cannot be invoked, an invocation of the utility is terminated by a signal or an invocation of the utility exits with a value of 255. DIAGNOSTICS
The xargs utility exits with a value of 0 if no error occurs. If utility cannot be found, xargs exits with a value of 127, otherwise if utility cannot be executed, xargs exits with a value of 126. If any other error occurs, xargs exits with a value of 1. SEE ALSO
echo(1), find(1), execvp(3) STANDARDS
The xargs utility is expected to be IEEE Std 1003.2 (``POSIX.2'') compliant. The -J and -R options are non-standard FreeBSD extensions which may not be available on other operating systems. HISTORY
The xargs command appeared in PWB UNIX. BUGS
If utility attempts to invoke another command such that the number of arguments or the size of the environment is increased, it risks execvp(3) failing with E2BIG. BSD
