Subject: [PATCH] gitweb: Allow arbitrary strings to be dug with pickaxe
Message-ID: <20070517023042.19611.59572.stgit@rover>
URL: https://gitlist.dev/e/20070517023042.19611.59572.stgit%40rover

```
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.
