Hi,

Just noticed on the git.kernel.org interface that when you do a search
for something that includes an "@" sign, then the "next page" link will
include "\@" instead and gitweb won't actually find anything on the next
page. No idea if that bug was fixed already somewhere else, but at least
it's visible on git.kernel.org.

This seems to fix it but I have no idea what it breaks. Command
injection should be stopped a few lines above that, and no other
parameter is ever quoted using quotemeta, so I'm not sure what the point
is, but I suppose it is actually necessary because the search text is
then wrapped into a regular expression or something?

Ah, I understand now. Here's a possibly complete fix.

From: Johannes Berg <johannes@sipsolutions.net>
Subject: quote $searchtext only before use

$searchtext is used in two ways
(1) to do the search
(2) to put it back into the output

For (1) it needs to have meta chars quoted, but for (2) not, so quote
them only when needed.
