[RFC PATCH] An option parser for the sequencer

Hi,

I've decided not to support arbitrary command-line options in the instruction sheet. A typical instruction sheet will looks like this (inspired heavily by the rebase -i instruction sheet format):

pick 3b36854 t: add tests for cloning remotes with detached HEAD pick 61adfd3 consider only branches in guess_remote_head pick 8537f0e submodule add: test failure when url is not configured in superproject pick 4d68932 submodule add: allow relative repository path even when no url is set pick f22a17e submodule add: clean up duplicated code pick 59a5775 make copy_ref globally available pick c1921c1 clone: always fetch remote HEAD

For persisting one set of options for every "git cherry-pick"/ "git revert" invocation, I've decided to use a simple "key = value" format and put it in .git/sequencer/opts (to sit beside .git/sequencer/head and .git/sequencer/todo). For strategy-option, I thought it would be cute to separate the various options using ' | '. So, it'll look something like this in the end:

signoff = true mainline = 1 strategy-option = recursive | ours

The implementation is a little rough around the edges, but I'm pretty happy with the overall design: it looks like a scaled-down version of parse-options. Quite a lot of context is missing (where did sequencer.h come from?!), but I hope it's clear enough to convey the idea.

Thanks for reading.
