bug#15118: 24.3.50; Flymake uses unrelated patterns to match error messages

[Oleg Sivokon]

Hello,

This is not entirely a bug, rather a behaviour that could be greatly
improved.

While trying to debug my own code, which deals with Flymake I've
realized that no matter the major mode, Flymake will iterate over ALL
`flymake-err-line-patterns' patterns (this may be a lot of complicated
regular expressions) to match the error message just received. This is
both counterproductive and is difficult to debug. Would it be possible
that Flimake expose this variable for customization to those who want to
use it, and while running a check on the specific mode, only use the
regular epxression defined for that mode?

Best,

Oleg
