Bug#831755: print column numbers in error messages too

OK but if there are two of them, one near the front of line 71, one near
the back, the user will be sent on a wild goose chase for maybe hours probably,

That's why perl should print the column number as well as the row.

Emacs' compile-mode is ready for it.
