Re: Query on git commit amend

Now, whats the benefit of 

GIT_EDITOR=cat git commit --amend

over

git commit --amend -C HEAD

?

The latter preserves the original timestamp of the commit and other
environment variables like GIT_COMMITTER_NAME GIT_COMMITTER_EMAIL
whereas GIT_EDITOR=cat (or true or :) are equivalent to opening up the
commit in an editor and so consider these variables during execution.

For instance, you could say

$ GIT_EDITOR=cat GIT_COMMITTER_EMAIL=foo@bar.baz git commit --amend

and the commiter email would be set to foo@bar.baz

Gnus should be more complicated.
