Cool, thanks for implementing this!
But unfortunately this change collides with bc/submodule-status-ignored
(I added Brian to the CC) which is currently on its way to next. Your
patch will break the fix in the second commit, because that's only
enabled when the submodule script sees the --for-status option.
A solution for that would be to rebase your patches on top of pu, drop
the first two hunks of the change to git-submodule.sh and still pass
the --for-status option to git-submodule.sh. This would move adding the
comment characters into wt-status.c but will still enable the script to
honor the ignore=all setting when called by status.
Junio, what is our take on changing behavior of undocumented internally
used options? Do we have to add a new --for-status2 (which doesn't add
the comment characters) or is it ok to just change the behavior of the
existing option?
