Subject: [PATCH] Restore locale handling after regex caching
file_regcomp/file_regfree had the side effect of setting and restoring
locale C_TYPE to C to have predictable regex matching. With regcomp
caching file_regfree has been changed to be only called at destruction
time, which means the library changed the locale setting for anything
else as well. Restore old behavior by splitting save/restore into
separate functions which are surrounding regcomp() and regexec() only.
