  I get very unhappy when *I* am the server administrator and read
messages like this. ;-) Could you please mention the
\$git_versions_must_match in the text?

Something like the text (extension) proposed above?


Actually, J.H., if you are changing the default, you should also change the
message to mention that checking versions is the default, and administrator
can turn it off[1].  It is incorrect if $git_versions_must_match defaults
to true.

[1] And you have to take into account that gitweb config file can not
exist, and neither $GITWEB_CONFIG nor $GITWEB_CONFIG_SYSTEM needs to be
non-empty.  J.H., are you really, really sure that it is a good idea to
have version check turned on by default, in light of this issue?
