Since 1.7.0 there a three reasons a submodule is considered modified
against the work tree: It contains new commits, modified content or
untracked content. Lets show all reasons in the long format of git status,
so the user can better asses the nature of the modification. This change
does not affect the short and porcelain formats.
Two new members are added to "struct wt_status_change_data" to store the
information gathered by run_diff_files(). wt-status.c uses the new flag
DIFF_FORMAT_SUBMODULES to tell diff-lib.c it wants to get detailed dirty
information about submodules.

So here is the promised patch teaching "git status" to show explicit
dirtiness information for submodules. Instead of just showing a
submodule as modified, it prints the reason(s) why the submodule is
considered modified along with a new hint line (thanks to Sergio
Callegari for bringing that last one up):
# Changed but not updated:
# (use "git add <file>..." to update what will be committed)
# (use "git checkout -- <file>..." to discard changes in working directory)
# (commit or discard the untracked or modified content in submodules)
#
# modified: sub (new commits, modified content, untracked content)
(Note: The part in behind the submodule name is not colored like
"modified:" and the name itself but like the header above for better
visibility)
I am not so proud of DIFF_FORMAT_DIRTY_SUBMODULES, the new flag i
introduced to tell run_diff_files() it should gather the information
needed even if we don't want patch output. It isn't a "format" per se,
but i couldn't come up with a better way to do this. Opinions?
