Re: [PATCH] (compilation-error-regexp-alist-alist): added regexps for ruby backtraces, ruby's Test::Unit output, cucumber output.

[Aleksei Gusev <aleksei.gusev@gmail.com>]

Is there any chance to get apply this patch on trunk? Maybe I do
something wrong in codebase?

I think many rubists will be very appreciated if Emacs will know about
ruby backtraces out of the box. ;]
