Replaced USAGE and LONG_USAGE with OPTIONS_SPEC
Signed-off-by: Jay Soffian <jaysoffian@xxxxxxxxx>
---
Okay, I'm pretty sure this is correct now. make test passes, and it also
passes my "it looks right" test after having gone over it a few times.
This isn't quite ready for inclusion yet though because I want some feedback:
* There is one semantic change. You can't use "-s=<strategy>" anymore. That's not
really proper usage of a short option (it's either "-s<strategy>" or
"-s <strategy>"). Is it okay to not accept the "-s=<strategy>" form?
* Is it worth doing this at all? If the plan is to rewrite everything as
builtins I kinda feel like I'm wasting my time. If not, I'll work on doing
this for all the other scripts which are missing an OPTIONS_SPEC. Then maybe
they can all be merged at once?
* You can see I added the GIT_PULL_DEBUG_ARGS blob. Frankly, I can't really
think of a good way to test this change other than to do something like that
and then add a test for each individual option. But that's going to really
bloat the test suite. Is it worth it to do this for every script? Or is
passing the existing test suite and enough eyeballs looking at it in next
good enough? Can you think of another way to check for regressions?
