Subject: diff --cumulative is a sub-option of --dirstat
X-Git-Tag: v1.6.0.2~19
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=f88d225feb117f0429540da90b2552e198fa2e82;p=git.git

diff --cumulative is a sub-option of --dirstat

The option used to be implemented as if it is a totally independent one,
but "git diff --cumulative" would not mean anything without "--dirstat".

This makes --cumulative imply --dirstat.
