This enhances core.logallrefupdates by allowing it to take
"heads" as the value as well, which causes git to create missing
reflog files automatically only for branch heads. Usually tags
are create-once-and-live-forever, and it is irritating to see
reflog files created automatically every time a new tag is made.
As before, boolean "true" means create missing reflog files for
all refs.
---
* Setting it to "tags" is not supported, as it does not make
much sense wanting to log only tag updates.
Come to think of it, it might make sense to change the
meaning of "true" to do what this patch does. I do not think
of reasons to create missing reflog for tags automatically
anyway.
Opinions?
