[PATCH v5 0/3] rebase: give precise error messages

[Kaartic Sivaraam <kaartic.sivaraam@gmail.com>]

The tip of the v4 of this patch can be found at [1]. It was a revamp
sent by Junio mostly touching [PATCH v2 1/3] of the series. I've updated
it a little to add in something of my taste ;-)

There's only one concern that still bothers me a little. With the current
code you would see the following,

    $ git rebase origin/maint 3013dff86
    Current branch 3013dff86 is up to date.

That doesn't look good, does it? How about we overcome the issue of
handling this case and the HEAD case done in 3/3 by simplifying the
message as shown in the following diff,

diff --git a/git-rebase.sh b/git-rebase.sh
index 0f379ba2b..4d5400034 100755
--- a/git-rebase.sh
+++ b/git-rebase.sh

+               say "$(eval_gettext "\$branch_name is up to date, rebase forced.")"
        fi
 fi

I guess this one is much better than 3/3 of this series as it handles
any kind of case by making no assumptions.

Thoughts ??


Note: In case you're wondering where's v3 of this series, there wasn't
a v3 series but there was a v3 PATCH of 3/3 [2].

Kaartic Sivaraam (3):
  rebase: consistently use branch_name variable
  rebase: distinguish user input by quoting it
  rebase: rebasing can also be done when HEAD is detached
