(That also gets rid of the minor strangeness of my series to introduce an
overly broad `suffix` and use it only for resetting color, not actually
for giving any textual suffix.)

Thanks for lots of good input. Doing the indenting in the error does
mean that to indent properly, the translator needs to know that it is an
error, and not a warning. Or one could say that they would need to know
the amount of indentation anyway so that they can know where to wrap
optimally.
Another consequence is that if we can emit a certain string as either,
e.g., a warning or an error depending on the context, we need to address
that. Using contexts, of course. Thank you for the hint about that. (I
have not checked if we actually have such "this is a warning or an
error"-strings currently.)
Somehow it feels slightly cleaner to me, at least on first thought, to
try to decouple the indenting from the translating and line-wrapping.
But as noted above, the indenting does affect how the line-wrapping
should/may be done.
I won't have as much time as I'd like for tinkering with this the next
week, or even weeks. Hopefully when I do get around to it, I will have
processed all the very good input I have received and turn that into
something good.
Thanks,
Martin
