NAME
       unwrapdiff - demangle word-wrapped patches

SYNOPSIS
       unwrapdiff [-v] [file...]

       unwrapdiff {--help | --version}

DESCRIPTION
       unwrapdiff demangles patches that have been word-wrapped, in an attempt to make them useful.

       The  corrected  diff is sent to standard output. Note that you will probably need to use the -l option when applying the patch, in order to
       ignore any whitespace differences there may be.

OPTIONS
       -v     Verbose operation. A list of lines that are modified in a way that might be wrong is sent to stderr.

       --help Display a short usage message.

       --version
	      Display the version number of unwrapdiff.

LIMITATIONS
       Some heuristics are used to decide whether use a space to recombine a wrapped line, or just join them together. Currently this is  done	by
       comparing with last three characters of a line with the first two characters of its continuation, and using a space of any of them are dif-
       ferent.

       The patch needs to have been valid before being word-wrapped.

       The last line of a hunk is nearly always ambiguous. If the next line begins ``@@'', ``Index:'', ``diff'' or ``---'' then it is taken to	be
       complete; otherwise it is unwrapped using the next line.
