of a malloc'ed buffer in regexec() in cases where the required
buffer size is small.
This will help us avoid a malloc/free pair when executing mod_rewrite
rules that use $1/$2/etc to reference sequences in the matched pattern.
Note: I've also submitted this change as a patch for PCRE, but because
the next PCRE release isn't planned until later this year I'm
committing it to the httpd-2.0 copy of PCRE in the meantime.
