[PATCH 0 of 3] Add hashdigits global option (with minor improvements).

[Eric Hopper]

Note: This new version includes some minor improvements over the
previous.  The documentation for hashdigits in help is slightly better.
And a test that checked for ui.verbose or ui.debugflag has been changed
to ui.verbose since ui.verbose is implied by ui.debugflag.

This is a set of changes to both improve global option processing in
some small ways as well as add a global option to allow you to set the
number of hash digits printed by default in the output of various
commands.

I am weird and I prefer referring to revisions with their full hash
values even though 12 digits is enough that it will likely uniquely
identify every revision in a repository with a million changesets.  I've
long maintained a patch that allows me to do this without using the
--debug flag, and I thought that a patch that allowed this to be
controlled more flexibly might be something a lot of people would want.

A config option is added as well.  The 'hashdigits' option in the 'ui'
section.

[ui]
hashdigits=12
