Subject: gitweb: Allow arbitrary strings to be dug with pickaxe
X-Git-Tag: v1.5.2~12

gitweb: Allow arbitrary strings to be dug with pickaxe

Currently, there are rather draconian restrictions on the strings accepted
by the pickaxe search, which degrades its usefulness for digging in code
significantly. This patch remedies mentioned limitation.
