This is an awesome contribution, thank you. I read the pull request where
you tried to add this support into flycheck
(https://github.com/flycheck/flycheck/pull/295) and noticed that you're
having a problem with the way error messages are formatted. Mostly they're
formatted this way to make it easier for human programmers to read, not for
other programs to parse. I'd be happy to propose a change to the Mercury
compiler that provides messages that are easier for flycheck and other
programs to parse.
