multiline_range breaks if an empty match is found

[buildmine10]

This is probably bad practice on my part when writing regex patterns. But I was testing to have multiline_range extract entire line. I tried this pattern /^.*/ which matches both empty lines and lines with stuff on them.

I did not expect going through the results to never end. I think when it gets to an empty line, it isn't removing anything from whatever buffer is pulled from.
