builtin-remote: new show output style for push refspecs
The existing output of "git remote show <remote>" with respect to push ref specs is basically just to show the raw refspec. This patch teaches the command to interpret the refspecs and show how each branch will be pushed to the destination. The output gives the user an idea of what "git push" should do if it is run w/o any arguments. Example new output: 1a. Typical output with no push refspec (i.e. matching branches only) $ git remote show origin * remote origin [...] Local refs configured for 'git push': master pushes to master (up to date) next pushes to next (local out of date) 1b. Same as above, w/o querying the remote: $ git remote show origin -n * remote origin [...] Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) 2a. With a forcing refspec (+), and a new topic (something like push = refs/heads/*:refs/heads/*): $ git remote show origin * remote origin [...] Local refs configured for 'git push': master pushes to master (fast forwardable) new-topic pushes to new-topic (create) next pushes to next (local out of date) pu forces to pu (up to date) 2b. Same as above, w/o querying the remote $ git remote show origin -n * remote origin [...] Local refs configured for 'git push' (status not queried): master pushes to master new-topic pushes to new-topic next pushes to next pu forces to pu 3. With a remote configured as a mirror: * remote backup [...] Local refs will be mirrored by 'git push' Signed-off-by: Jay Soffian <jaysoffian@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
