Subject: Skip excessive blank lines before commit body
X-Git-Tag: v1.5.0-rc1~105
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=f3a47405bb27846d62d20b056817f9c7d320e2db;p=git.git

Skip excessive blank lines before commit body

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).
