[PATCH 0/4] Documentation: Auto-generate merge tool lists

Refactor the mergetool-lib so that we can reuse it in
Documentation/Makefile.  The end result is that the
diff.tool and merge.tool documentation now includes
an auto-generated list of all available tools.

This applies on top of jk/mergetool in pu.

David Aguilar (4):
  mergetool--lib: Simplify command expressions
  mergetool--lib: Improve the help text in guess_merge_tool()
  mergetool--lib: Add functions for finding available tools
  doc: Generate a list of valid merge tools
