I agree in principle that we should enable -fshow-column by default.
Obviously, it will break some existing scripts, but I tend to think that
for something like this that is OK. Any scripts which break are already
slightly broken in that preprocessor error messages already display a
If you haven't already done so, please check that the emacs next-error

When we have good caret diagnostics it would also be nice to enable them
by default. However, that is a much bigger change. Does anybody have
an opinion on that?
