[PATCH 0/3] Add a function skip_prefix_if_present()

[Michael Haggerty <mhagger@alum.mit.edu>]

These patches apply on top of gitster/nd/more-skip-prefix.

I noticed that Duy's new function skip_prefix_defval() was mostly
being called with its first and third arguments the same.  So
introduce a function skip_prefix_if_present() that implements this
pattern.

Michael Haggerty (3):
  Add and use a function skip_prefix_if_present()
  diff_scoreopt_parse(): use skip_prefix_if_present()
  rev_is_head(): use skip_prefix()
