/**
TODO/FIXME/NICE-TO-HAVE: we "really should" process the CLI flags
in the order they are provided on the CLI, as opposed to the
order they're defined in the defs array. The current approach is
much simpler to process but keeps us from being able to support
certain useful flag-handling options, e.g.:
f-tag -a artifact-id-1 --tag x=y --tag y=z -a artifact-id-2 --tag a=b...
The current approach consumes the -a flags first, leaving us
unable to match the --tag flags to their corresponding
(left-hand) -a flag.
Processing them the other way around, however, requires that we
keep track of which flags we've already seen so that we can
reject, where appropriate, duplicate invocations.
We could, instead of looping on the defs array, loop over the
head of fcli.argv. If it's a non-flag, move it out of the way
temporarily (into a new list), else look over the defs array
looking for a flag match. We don't know, until finding such a
match, whether the current flag requires a value. If it does, we
then have to check the current fcli.argv entry to see if it has a
value (--x=y) or whether the next argv entry is its value (--x
y). If the current tip has no matching defs entry, we have no
choice but to skip over it in the hopes that the user can use
fcli_flag() and friends to consume it, but we cannot know, from
here, whether such a stray flag requires a value, which means we
cannot know, for sure, how to process the _next_ argument. The
best we could do is have a heuristic like "if it starts with a
dash, assume it's a flag, otherwise assume it's a value for the
previous flag and skip over it," but whether or not that's sane
enough for daily use is as yet undetermined.
If we change the CLI interface to require --flag=value for all
flags, as opposed to optionally allowing (--flag value), the
above becomes simpler, but CLI usage suffers. Hmmm. e.g.:
f-ci -m="message" ...
simply doesn't fit the age-old muscle memory of:
svn ci -m ...
cvs ci -m ...
fossil ci -m ...
f-ci -m ...
