Subject: Return 1 if no matches were found
X-Git-Tag: 1.1.17~1
X-Git-Url: https://git.sesse.net/?p=plocate;a=commitdiff_plain;h=31641da5750ed2b80697e605bf5b50c0a92264af

Return 1 if no matches were found

* plocate.1: Document this new behavior.
* plocate.cpp (do_search_file, main): Exit with code 1 if no matches were found.

This behavior is consistent with that of mlocate except with --limit=0, which
plocate rejects.
