Hi,

I was trying to rebuild some history and found myself trying to use some options with git merge which are available in git commit:

 git merge \
     --date "2013-12-31 23:59:59 +0000" \
     --author "Happy New Year <happy.new-year@gregorian.calendar>" \
     current-year

But unfortunately, unlike git commit, git merge doesn't support either --date or --author.

I can work around with environment variables:

 GIT_AUTHOR_DATE="2013-12-31 23:59:59 +0000" \
 GIT_AUTHOR_NAME="Happy New Year" \
 GIT_AUTHOR_EMAIL="happy.new-year@gregorian.calendar"  \
 git merge current-year

But I'd like to know if there's a specific reason for git merge to not support --date and --author ?

Regards.
