[PATCH 0/6] Advanced --oneline layout

Still a toy series (previous discussion [1]) but it's getting close to something useful.

This introduces three placeholders %<, %> and %<> for left/right/center align the next placeholder. Any of them can be followed by '|' to make the next placeholder use up to the Nth column.

It's pretty useful already. You should be able to do multi column layout on your wiiide terminal. It might even be useful in multi-line printouts (e.g. we can relayout the commit header)

There are a few things we can improve:

 - utf8-only support does not sound nice (even though I'm
   perfectly happy with it). At some point I think it'll be easier for
   us to declare all internal strings be in utf8 (or ascii in certain
   places), input/output routines are supposed to do the conversion.
   GNOME has gone this way since 2.0.
 - ellipsis to prevent too long text breaking layout
 - specifing "30% of my screen width" would be nice, but it could get
   complicated if users start to demand "30% width, but no less than 30
   columns and no more than 100 columns, and if blah blah"
