[PATCH v2 0/9] A natural solution to the @ -> HEAD problem

[Ramkumar Ramachandra <artagnon@gmail.com>]

Hi,

So, we're back with v2 of the series.  Six patches add comprehensive
tests to at-combinations, guarding against any future bugs.  [7/9] is
the most important part, where I've fixed branch_get() with a long
justification.  [8/9] and [9/9] are almost trivial.

As Felipe pointed out, [9/9] might require more documentation, but I
don't know where to put it.  Help in the area is appreciated.

I've excluded all @-parsing simplification in this series.  It will
come as a later series based on this one: I'm currently integrating
Felipe's work with mine.

Felipe: can I have your sign-off for the first three parts?

Thanks.

  t1508 (at-combinations): increase coverage
  t1508 (at-combinations): document @{N} versus HEAD@{N}
  t1508 (at-combinations): test with symbolic refs
  remote.c: teach branch_get() to treat symrefs other than HEAD
  sha1_name.c: fix @-parsing bug in interpret_branch_name()
  refs.c: make @ a pseudo-ref alias to HEAD
