Some brief testing suggests that Emacs handles the column number if
you remove the variable erlang-error-regexp-alist, the function
erlang-add-compilation-alist, and the two calls to the latter.  (That
function adds an entry to compilation-error-regexp-alist; remove it
manually or restart Emacs to try it out.)  I guess that function was
compensating for something that was missing in Emacs 19, but whatever
it was, it seems like my Emacs 24 doesn't need it...
