This is a sensible cleanup, though as I mentioned elsewhere, I think it
would make sense to come first before the other patch.
After this, fill_one is _almost_ identical to just calling
fill_textconv; the exception is that for the !DIFF_FILE_VALID case,
fill_textconv gives us an empty buffer rather than a NULL one.
What do you think of something like this on top (this is on top of your
patches, but again, I would suggest re-ordering your two, so it would
come as patch 2/3):
