Skip excessive blank lines before commit body

hjemli · Junio C Hamano · commit f3a47405bb27 · 2007-01-03T08:29:01.000-08:00
This modifies pretty_print_commit() to make the output of git-rev-list and
friends a bit more predictable.

A commit body starting with blank lines might be unheard-of, but still possible
to create using git-commit-tree (so is bound to appear somewhere, sometime).
