It hasn't been corrected yet, though - which I wouldn't mention, except
that the others I noted have, so it's possible that this was an

Unfortunately, no. I found it in the first place while going hog-wild
installing dict-compatible dictionaries, so I just use dict to access

I don't know formally, but in this instance it's because you're using
"VCD-related" as an adjective, and as such its component words need to
be bound together; a hyphen is simply the usual way of doing that. (This
may not be an official rule, but it applies universally for clear
comprehension as far as I'm concerned.)

Well, no. And I knew I was being nitpicky and annoying, I just didn't
want to get *too* nitpicky and annoying. There are limits, after all.

Will do if I can find them again, when I have a chance - which given the
hour may not be soon. (Too many things to do, not enough initiative to
get up and do them... and I work tomorrow.)

I've had problems trying to figure that one out myself; your suggestion
makes sense, but I'd be content with any (sane) official pronouncement
so I could be sure in future of getting it right.

The problem with both of these is that, for some of the same reasons as
I don't understand the code, I don't really know how most of the program
works well enough to improve on what descriptions I know about. I've
been picking things up here and there by mostly-lurking on the mailing
lists, but my overall knowledge is still quite limited.

I suppose I could go reading through the HTML documentation and so
forth, and see if I spot anything I could explain better... in my
copious spare time. :)

I actually took on the latter of these (printf --> mp_msg) once, but ran
into the problem of choosing what MSGT and MSGL to use. It was agreed to
define MSGL_FIXME, so that people who actually know that part of the
code well enough to make the decision could more easily find and change
the problem spots, but the question of what MSGT(s) to use was never
resolved and I ended up stopping work on the endeavour. If these two
problems can be resolved, I could start over again, but as things stand
my lack of knowledge of the code gets in the way.

One thing I could do regardless is keep a watch on this mailing list and
point out any commits with printfs or similar (sort of like I've been
doing with mistakes in these spellcheck commits); by itself this won't
fix the existing problems in that respect, but it would help prevent
them from getting any worse.

As to poorly-done text output - I'll keep my eyes open, and if I see
anything I can with confidence improve upon, I'll point it out.
Code-diving (or even just -searching) in search of these things will
have to wait at least until my work schedule slows down, which will
happen no later than November (but probably much earlier).

Well, I'm not sure (as noted) how much help I could be, and my own time
is more limited than I'm used to (though much less than it could be),
but if there's anything specific I *can* do feel free to ask; there's
little I like more than helping out.
