Subject: [PATCH 1/3] gitweb: support to globally disable a snapshot  
format

I added an optional variable, 'disabled', to to the
$known_snapshot_formats keys so that a Gitweb administrator can
globally enable or disable a specific format for snapshots.

All formats are enabled by default because project specific overriding
is disabled by default.

Please have all of the above after the "---" line.

And you do not need these four lines, as they match what you have in the
e-mail header.

"to to"?

We tend not to say "I did this and that" in our log messsages; order the
codebase to do certain new things, or order the maintainer to change the
code to make it do new things. e.g.

	Allow gitweb administrators to set in %known_snapshot_formats hash
	an optional key, 'disabled' for specific format.  This can be used
	to configure out individual formats.

That is not quite a good justification; but "all the formats have been
enabled so far, and installing an updated gitweb should not change the
existing behaviour" is.
