this is possibly a bug.

Summary: when using M-x grep-find, on a search word with camelCase, i get this error:
“Grep exited abnormally with code 123 at Mon Mar 16 17:22:46”.

Reproduce steps:

• start emacs 22.x with -q
• M-x grep-find
• Try to search a word with camelCase. e.g. “find . -name "*txt" - print0 | xargs -0 -e grep -nH -e pestiLence”
• Emacs gives the error mentioned above.

This is reproducible in:

• GNU Emacs 22.2.1 (powerpc-apple-darwin8.11.0, Carbon Version 1.6.0) of 2008-04-05 on g5.tokyo.stp.isas.jaxa.jp • GNU Emacs (powerpc-apple-darwin8.11.0, GTK+ Version 2.6.10) of 2009-03-01 on xahg5.local

This problem happens also when called with shell-command. e.g. M-x shell-command, then use
“find . -name "*txt" -print0 | xargs -0 -e grep -nH -e pestiLence”.

However, this does not happen when called in shell, e.g. M-x shell. Nor when i simply run it in a Terminal running bash. (so, prob not having to do with the unix's “find”, “grep”, “xargs” programs on my computer.)
