[PATCH 0/3] pretty: format aliases

[Will Palmer <wmpalmer@gmail.com>]

The following patch series adds the ability to configure aliases for
user-defined formats. The first two patches define new placeholders and
modify the output of existing placeholders to allow aliases to be more
consistent with the way builtin formats are handled. The final patch
adds support for the aliases themselves.

There were a couple of places where I wasn't entirely sure about which
color setting I should be following, but I've tried to be consistent
throughout. It may be that I could have simply followed diffopt's color
option in all cases, in which case various modifications to show_log()
were entirely unnecessary. I'll await judgement at the hands of one who
groks those sections more than I do, but I think what I've done feels
correct.

My original goal was to make it possible to define all of the builtin
formats as builtin aliases to format strings, but complications
regarding how --parents and --decorate would be handled require further
thought and discussion. For example, we could simply make
"--format=%H --decorate" synonymous with "--format=%H%d", but I'm not
sure if that feels clean enough.

For now, I think this is at a point where its good-enough to submit, if
only as a starting point for some discussion as to where to head next.
