Add a --dry-run option to git-send-pack.

Browse Source

in calls from git-push. With this flag set, git-send-pack
will not send any updates to the server.

@ -34,6 +34,9 @@ OPTIONS
Instead of explicitly specifying which refs to update,
update all heads that locally exist.
\--dry-run::
Do everything except actually send the updates.
\--force::
Usually, the command refuses to update a remote ref that
is not an ancestor of the local ref used to overwrite it.
