The existing output of "git remote show <remote>" is too verbose for the
information it provides. This patch teaches it to provide more
information in less space.
The output for push refspecs is addressed in followup patch.
Before the patch:
$ git remote show origin
* remote origin
URL: git://git.kernel.org/pub/scm/git/git.git
HEAD branch: master
Remote branch merged with 'git pull' while on branch master
master
Remote branch merged with 'git pull' while on branch next
next
Remote branches merged with 'git pull' while on branch octopus
foo bar baz frotz
New remote branch (next fetch will store in remotes/origin)
html
Stale tracking branch (use 'git remote prune')
bogus
Tracked remote branches
maint
man
master
next
pu
todo
After this patch:
$ git remote show origin
* remote origin
URL: git://git.kernel.org/pub/scm/git/git.git
HEAD branch: master
Remote branches:
bogus stale (use 'git remote prune' to remove)
html new (next fetch will store in remotes/origin)
maint tracked
man tracked
master tracked
next tracked
pu tracked
todo tracked
Local branches configured for 'git pull':
master rebases onto remote master
next rebases onto remote next
octopus merges with remote foo
and with remote bar
and with remote baz
and with remote frotz
$ git remote show origin -n
* remote origin
URL: git://git.kernel.org/pub/scm/git/git.git
HEAD branch: (not queried)
Remote branches: (status not queried)
bogus
maint
man
master
next
pu
todo
Local branches configured for 'git pull':
master rebases onto remote master
next rebases onto remote next
octopus merges with remote foo
and with remote bar
and with remote baz
and with remote frotz
