Hmm. Isn't "expand tabs" orthogonal to the rest of the pretty format?
That is, couldn't one want "--pretty=fuller, but with tabs expanded"?
I don't personally care much myself, and certainly we don't need to
support "--expand-tabs" for every format until somebody actually wants
them enough to implement it. I just don't want to see us painted into a
corner where we have to support an awkward interface forever (e.g., the
way we had to retrofit the orthogonal "local" concept onto the --date
code).
E.g., start with:
- only CMIT_FMT_MEDIUM expands tabs (and does so by default)
- passing --no-expand-tabs suppresses this behavior
- passing --expand-tabs is an error for now; if people care later,
they can add support for other formats (naively this is trivial, but
I suspect there are some corner cases around things like
--pretty=raw, so unless somebody wants to work on it now, I don't
think we need to).
