I sometimes wonder what value the message is giving us.
For example, while reviewing a patch in my Emacs session, I may say
| git am -s3c RETURN
which runs the command on the contents of the e-mail I am reading,
to apply the patch. After that, I would go to a separate terminal
and do things like git show -U20, etc. Once I am done, I reset
the temporary commit away, and get this:
$ git reset --hard HEAD^
HEAD is now at ce5cf6f Merge git://github.com/git-l10n/git-po
or often it is
$ git reset --hard ko/master
HEAD is now at ce5cf6f Merge git://github.com/git-l10n/git-po
In either case, I know where I am resetting to, so HEAD is now at
is a less than useful noise. If it contained HEAD was at ..., it
may let me realize that I was still going to use the contents in
some other way and quickly go back to it with another reset, with
cut and paste or with HEAD@{1}. In either case, showing the tip of
what I just discarded seems to be a lot more useful information than
what we are currently giving the users.
Unless you use a git aware prompt, it's always good to know where your
HEAD is ;) Just think of:
git reset --hard HEAD^2
HEAD is now at ...
Oh, I meant HEAD~2 aka HEAD^^ ...
In that case, information about HEAD@{1} might be useful but is not
necessary, unless you are leaving behind a detached HEAD.
Cheers,
Michael
