But in the form you are using, you have to reserve that space anyway.
Consider an error marker at the end of the line:
QUERY: select 'text that is long enough to be a problem':QUERY: ^ on
line1
Having to leave space for "on line 1" at the right end is not better
than putting "line 1:" at the left end.

It seems confusing to me. The cursor is just a marker. Consider also
the next step up from this scheme: instead of assuming a dumb terminal,
suppose you can use color or underlining or reverse-video or some such.
Then you might want to do just one line of output:
QUERY: SELECT foo FROM bar WHRE baz; ----
where my underlining represents using the terminal's highlight ability.
With such a scheme, putting LINE n on the same line fits naturally.

Sure, but you have to buy into that anyway if you are going to do "...".
It's not going to add more than about one strlen() call to what you need
to do.

Hmm, that's a good point, although perhaps you could insert a note to
translators to add space as needed to make the two strings the same
length.
