This makes git-applymbox verify that the index matches the current HEAD before it starts applying patches. Otherwise, you might have updated the index with unrelated changes, and the first patch will commit not just the patch from the mbox, but also any changes you had in your index.

## "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"
|
|
##
|
|
## applymbox [ -k ] [ -q ] (-c .dotest/msg-number | mail_archive) [Signoff_file]"
|
|
##
|
|
## 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.
