Recently git-status learned to display the state of the git
sequencer in long form to help the user remember an interrupted
command. This information is also useful in short form to
humans and scripts, but no option is available to boil it down.
Teach git-status to report the sequencer state in short form
using a new --sequencer (-S) switch. Output zero or more
simple state token strings indicating the deduced state of the
git sequencer.
Introduce a common function to determine the current sequencer
state so the regular status function and this short version can
share common code.
Add a substate to wt_status_state to track more detailed
information about a state, such as "conflicted" or "resolved".
Move the am_empty_patch flage out of wt_status_state and into
this new substate.
State token strings which may be emitted and their meanings:
merge a git-merge is in progress
am a git-am is in progress
rebase a git-rebase is in progress
rebase-interactive a git-rebase--interactive is in progress
cherry-pick a git-cherry-pick is in progress
bisect a git-bisect is in progress
conflicted there are unresolved conflicts
resolved conflicts have been resolved
editing interactive rebase stopped to edit a commit
edited interactive rebase edit has been edited
splitting interactive rebase, commit is being split
I also considered adding these tokens, but I decided it was not
appropriate since these changes are not sequencer-related. But
it is possible I am being too short-sighted or have chosen the
switch name poorly.
