[PROPOSAL] Allow %r{} syntax for multiline regexps

[ixti]

IMHO %r{} looks better for multi=line regexps:

RE = %r{
  ^
    (...)
    (...)
  $
}x

# vs

RE = /
  ^
    (...)
    (...)
  $
/x

Seems pretty subjective to me, but I've noticed others share this particular preference.

@bbatsov coding styles are subjective things in general ;))

True that. I guess we can add an option to use a different delimiter for multi-line regexps.
