feature suggestion: git symbolic-ref --create-reflog

[Chris Jerdonek <chris.jerdonek@gmail.com>]

This email is to suggest the idea of adding a --create-reflog flag to
git-symbolic-ref in the same way that git-update-ref has one.

(This suggestion relates to my previous email with subject "ambiguous
git-reflog output for symbolic refs," which points out an issue with
git-reflog for symbolic refs that don't have a reflog:

)

To illustrate, if you create a symbolic ref in the standard set, it
creates a reflog for the symbolic ref:

$ git symbolic-ref -m create-symref refs/heads/my-new-symref refs/heads/master
$ cat .git/logs/refs/heads/my-new-symref
0000000000000000000000000000000000000000

But if you create one outside of the standard set, it doesn't (and
there's no --create-reflog option like there is with git-update-ref):

$ git symbolic-ref -m create-symref refs/foo/my-new-symref refs/heads/master
$ cat .git/logs/refs/foo/my-new-symref
cat: .git/logs/refs/foo/my-new-symref: No such file or directory

I do notice that Jeff's "one-shot config" approach that he suggested
in reply to an earlier email of mine [1] (with subject line "create
reflog for reflog-less ref") provides a workaround in the absence of
this option:

$ git -c core.logAllRefUpdates=always symbolic-ref -m one-shot
refs/foo/my-symref refs/heads/master
$ cat .git/logs/refs/foo/my-symref
0000000000000000000000000000000000000000
