[PATCH v10 0/5] git log -L

From: Thomas Rast <trast@inf.ethz.ch>

This adds a bunch of fixes and failing tests for invalid -L arguments; as Antoine discovered, some variations would segfault v9.

I also changed the beginning of parse_range_funcname (in patch 4/5), which now also lets you backslash-escape a : in a funcname regex. The old version was based on the assumption that there could only be a ':' in the string if we were coming from scan_range_arg, which made it a bit hard to read.

Bo Yang (2):
  Refactor parse_loc
  Export rewrite_parents() for 'log -L'

Thomas Rast (3):
  Implement line-history search (git log -L)
  log -L: :pattern:file syntax to find by funcname
  Speed up log -L... -M
