This is an attempt to allow '-' everywhere a revision is normally allowed. I previously attempted this as a microproject and the subject was disscussed at : http://article.gmane.org/gmane.comp.version-control.git/265672

Currently, something like '-~2' does not work. I tried tracing the execution of, say 'log -~2' vs 'log master -~2' and noticed when calling dwim_ref() with '-~2', it returns 0 (no refs found) whereas when given 'master~2', it returned non-zero. However I'm not sure how exactly dwim_ref() works.

Kenny Lee Sin Cheong (4):
  Add "-" as @{-1} support for the rev-parse command
  t1505: add tests for '-' notation in rev-parse
  Handle arg as revision first, then option.
  t0102: add tests for '-' notation
