 too aggressive

[Message part 1 (text/plain, inline)]

I believe this regex for cucumber is not precise enough. Specifically,
it was picking up this indentation in an error message from GHC:

Main.hs:195:1: error: [GHC-44432]
    The type signature for ‘apathway’ lacks an accompanying binding
    Suggested fix:
      Perhaps use one of these:
        ‘foo’ (Defined at Main.hs:196:1),
        ‘foo’ (Defined at Main.hs:216:1)

It picked up this as being error messages which I believe it shouldn’t have:

   ‘foo’ (Defined at Main.hs:216
   ‘foo’ (Defined at Main.hs:216

This change just ignores it if there is remaining space. Probably it
still needs to be refined, but this at least avoids this false positive
for me.
