Subject: hook: move unsorted_string_list_remove() to string-list.[ch]
X-Git-Tag: v2.54.0-rc1~33^2~11
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=add3564d2f2804ad37b9af773ec6420b497a1725;p=thirdparty%2Fgit.git

hook: move unsorted_string_list_remove() to string-list.[ch]

Move the convenience wrapper from hook to string-list since
it's a more suitable place. Add a doc comment to the header.

Also add a free_util arg to make the function more generic
and make the API similar to other functions in string-list.h.
Update the existing call-sites.
