[PATCH 2/3] checkout, commit: remove confusing assignments to rev.abbrev

[Jonathan Nieder <jrnieder@gmail.com>]

Since they do not precede setup_revisions, these assignments of 0 to
rev.abbrev have no effect.

v1.7.1.1~17^2~3 (2010-05-03) taught the log --format=%h machinery
to respect --abbrev instead of always abbreviating, so we have to pay
attention to the abbrev setting now.
