[PATCH] gitweb: escape searchtext and parameters for replay

[Michael J Gruber <git@drmicha.warpmail.net>]

Search texts may very likely include characters like '@' when grepping
for author names. Currently, gitweb produces first/prev/next links with
incorrectly escaped characters.

Make gitweb escape searchtext and parameters which are reused in href()
when replay is set. (cgi params are de-escaped when put into the
parameter dictionary and need to be re-escaped when reused.)

Maybe something like this? Highly untested!

Cheers,
Michael
