I made a new pull request based on the ongoing work.
What do you think and can we get some users to test behaviors on a variety of platforms?

Subject: ant wrapper script testing
I have been doing some work on trying to correct errors in the ant shell script with how special characters and whitespace and handled in arguments.
I have a scratch branch in github. I do forced pushes as I clean it up and try new things, so beware forking.
I do trials by running a script test.sh:
./bin/ant --execdebug \
"-Ddoublespace= " \
where test.xml is simply
<echo message="hello world"/>
The trailing _ characters are so that echo task does not trim the output for trailing whitespace scenarios.
The only solution I have found to date that avoids all behavior quirks such as echo, sed, awk, and whitespace handling is a bashism/ksh/zsh-ism. So that does not work for ubuntu's /bin/sh. I have not figured out a universal correct script for dash (ubuntu) yet.
It may be worth detecting those shells to leverage that when we can.
I have run the script with bash, ksh, zsh, and dash under Ubuntu and Mac.
Csh and tcsh do not seem to work (do we expect them to?)
I do not have an HP-UX or Solaris setup yet (though there are vbox images for Solaris).
I may not have much time for more testing today, but would appreciate any advise:
1) from people with Solaris and HP-UX and AIX
2) thoughts on introducing shell detection and bashisms into the script
3) how to do a clean string substitution or sed/awk based replacement that doesn't munge newline and trailing spaces
4) anything else that appears fishy in the test cases
