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

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.

Ramkumar Ramachandra (6):
  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
