gitweb: link to 7-char+ SHA-1s, not only 8-char+
Change the minimum length of an abbreviated object identifier in the commit message gitweb tries to turn into link from 8 hexchars to 7. This arbitrary minimum length of 8 was introduced in bfe2191 ("gitweb: SHA-1 in commit log message links to "object" view", 2006-12-10), but the default abbreviation length is 7, and has been for a long time. It's still possible to reference SHA-1s down to 4 characters in length, see v1.7.4-1-gdce9648's MINIMUM_ABBREV, but I can't see how to make git actually produce that, so I doubt anyone is putting that into log messages in practice, but people definitely do put 7 character SHA-1s into log messages. I think it's fairly dubious to link to things matching [0-9a-fA-F] here as opposed to just [0-9a-f], that dates back to the initial version of gitweb from 161332a ("first working version", 2005-08-07). Git will accept all-caps SHA-1s, but didn't ever produce them as far as I can tell.
