The patch looks obviously correct; "our %known_snapshort_formats" maps a
name to a hashref, but the current code makes a nonsense assignment,
essentialy doing ($fmt, %opt) = ($name, $hashref), but what would I
know...  I am not using gitweb actively.

These lines come from 1ec2fb5 (gitweb: retrieve snapshot format from
PATH_INFO, 2008-11-02) by Guiseppe.

Judging from the "git shortlog -n -s --grep=PATH_INFO gitweb" output, I
think I should have heard from either Guiseppe and Jakub by now if this
patch is desired.  Pinging them...
