No, I am not saying that.

If git-instaweb is invoked *without* --reuse-config, the gitweb_config.perl
would be regenerated whether it exists or not, overwriting your changes.

If git-instaweb is invoked *with* --reuse-config, the gitweb_config.perl
would be generated if it does not exist (so if you delete gitweb_config.perl
and then run 'git instaweb --reuse-config' it would not fail), and reused
if it does exist.

  test "$no_reuse" = true || test ! -e "$GITWEB_CONFIG" && gitweb_conf

or something like that (the test if $GITWEB_CONFIG file exists might be
moved to the fragment of code that sets no_reuse to true instead).
