[PATCH v4 0/3] Expanding tabs in "git log" output

So here is the fourth try.  Previous round are at $gmane/289694,
$gmane/289166, and $gmane/288987.

I didn't quite find a good order to build this progressively, so
this series:

 - First adds the internal machinery and explicit --expand-tabs.
   This keeps Linus's authorship, but is different in that it is not
   enabled by default;

 - Then enable --expand-tabs by default for selected pretty formats;

 - And optionally, allow custom tab-width to be used.

Junio C Hamano (2):
  pretty: enable --expand-tabs by default for selected pretty formats
  pretty: allow tweaking tabwidth in --expand-tabs

Linus Torvalds (1):
  pretty: expand tabs in indented logs to make things line up properly
