[RFC][Fortran,patch] %C error diagnostic location

Tobias Burnus
Hi all,

my feeling is that %C locations are always off by one, e.g., showing the
(1) under the last white-space character before the place where the
error occurred – the match starts at the character after the

That bothered my for a while – but today, I was wondering whether one
shouldn't simply bump the %C location by one – such that it shows at the
first wrong character and not at the last okay character.

What do you think?

Another observation (unfixed): If gfortran buffers the error, the %C
does not seem to get resolved at gfc_{error,warning} time but at the
time when the buffer is flushed – which will have a reset error location.

Looks good.
