Subject: gitweb: improve snapshot error handling
X-Git-Url: https://git.ladys.computer/Gitweb/commitdiff_plain/9dba264f8c80ea663327734759f3557a5a2c7fc15071908cbd53cc2f008c12b5

gitweb: improve snapshot error handling

The last check in the second block of checks in the &git_snapshot routine
is never executed because the second to last check is a superset of the
last check.

Switch the order of the last two checks. It has the advantage of giving
clients a more specific reason why they cannot get a snapshot format if
the format they have chosen is disabled.
