Although it may be good to note that command line length does not really play a role in this case, since "for" is a shell keyword and not an external command, so the length of the list should be more or less limited by memory...

It is not only bash, dash and Bourne shell do this too. It is also not specified by Posix, so ksh is the exception..

pom_xpath_inject
POM_XPATH_INJECT(7) Java Packages Tools POM_XPATH_INJECT(7)
NAME
pom_xpath_inject - inject XML code into POM file
SYNOPSIS
%pom_xpath_inject XPath [XML-code] [POM-location]
DESCRIPTION
This macro patches specified POM file appending some code as childreen of all XML nodes described by the XPath expression.
XPath is an expression describing a set of XML nodes in the POM file to which child code is to be appended. It must be a properly formated
XPath 1.0 expression, as described in http://www.w3.org/TR/xpath/.
POM location can be either a full path to the POM file, or a path to the directory containing pom.xml. If POM location is not given then
pom.xml from current working directory is used.
EXAMPLES
%pom_xpath_inject pom:project "<packaging>war</packaging>" - this call sets packaging of POM in current working directory to war.
BUGS
POM files use a specific namespace - http://maven.apache.org/POM/4.0.0. Currently this namespace needs to be explicitly specified in all
XPath POM macros by prefixing all node names with pom:.
