Re: Git question rewarding git merge and its exit codes

["Iván Expósito" <byjokese@gmail.com>]

Thanks so much for the suggestions. I already thought on the first
one, comparing the SHA's, but not always same SHA's will ensure the
merge will have changes to be made (ideological would be the correct,
but some workflows won't ensure it). Will take a look using
-no--commit and take a look with git status and the porcelain flag.
That may be easier and more secure.

Thanks for the answers.
