x/re/ repeatedly sets . with matches until the input
is exhausted.  so i don't think i understand your example.
how does /.*\n/{(.*\n)|.*\n(.*\n)|} match anything
but the tautological .*\n|?  for example, if the input
is "line1\nline2\n", then . is in turn "line1\n" and "line2\n",
and both match .*\n|.

where do the actions go in your example?
