Re: [PATCH] shell portability: Use sed instead of non-portable variable expansion

What happens if you write these as

	QUERY_STRING=${1#*\?} \
	PATH_TRANSLATED=$HTTPD_DOCUMENT_ROOT_PATH/${1%%\?*} \

i.e., drop the double-quotes?

Interesting. Your conjecture is that the shell may be dropping the
backslash inside dq context when it does not understand what follows the
backslash, i.e. "\?"  -> "?", losing the quote. I find it very plausible.

If that is the case, either the above or my [?] would work it around, I
would think.

Thanks.
