"empty ident not allowed" error makes commit-tree fail, so we are already safer in that we would not end up with commit objects that have bogus names on the author or committer fields. However, before commit-tree is called there are already changes made to the index file and the working tree. The operation can be resumed after fixing the environment problem, but when this triggers to a newcomer with unusable gecos, the first question becomes "what did I lose and how would I recover". This patch modifies some Porcelainish commands to verify GIT_COMMITTER_IDENT as soon as we know we are going to make some commits before doing much damage to prevent confusion.

## "dotest" is my stupid name for my patch-application script, which
|
|
## I never got around to renaming after I tested it. We're now on the
|
|
## second generation of scripts, still called "dotest".
|
|
##
|
|
## Update: Ryan Anderson finally shamed me into naming this "applymbox".
|
|
##
|
|
## You give it a mbox-format collection of emails, and it will try to
|
|
## apply them to the kernel using "applypatch"
|
|
##
|
|
## The patch application may fail in the middle. In which case:
|
|
## (1) look at .dotest/patch and fix it up to apply
|
|
## (2) re-run applymbox with -c .dotest/msg-number for the current one.
|
|
## Pay a special attention to the commit log message if you do this and
|
|
## use a Signoff_file, because applypatch wants to append the sign-off
|
|
## message to msg-clean every time it is run.
|
|
##
|
|
## git-am is supposed to be the newer and better tool for this job.
