Subject: [PATCH] Only link local titles on Special:Search

Anything else is confusing, especially given the message text
we have there.

Example:
https://www.mediawiki.org/wiki/Special:Search?search=en%3Afoo&fulltext=1

Also fix the documentation of Title::isLocal as that was misleading
and fooled me (in PS1).
