Subject: builtin-commit: Include the diff in the commit message when verbose.
X-Git-Tag: v1.5.4-rc0~78^2~11
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=99a12694582e2148fcd492f1eedaddcfe2a21621;p=git.git

builtin-commit: Include the diff in the commit message when verbose.

run_diff_index() and the entire diff machinery is hard coded to output
to stdout, so just redirect that and restore it when done.
