We may not have to, after all.  Reading the OMake sources, it very much looks 
like errors are indented by exactly 6 spaces, which means that we can replace 
(* " ") with (? "6 spaces") which is a lot faster.

Having done that, it turned out that recognising ruby-Test::Unit errors 
depended on the old 'omake' regexp rewriting (another reason to disable omake 
by default, perhaps), so that regexp had to be fixed as well.

Along with the two previous patches (for msft, watcom and maven), this should 
reduce the cost of long lines to something more tolerable for the time being.
