Fix TAP nearest to support multiline match

@janko I know understand why this isn't working, it's because test#base#nearest_test_in_line goes through line by line which means that multi-line matching for test nearest isn't currently possible. Any suggestions on how to proceed with this?

Not sure, line-by-line matching is needed to detect nesting. I don’t know how to handle multiline matching as well 🤔

What if test nearest match started at a single line and then kept expanding in range in both directions till a match was found? For example I run it at line 12 and it searches that line, then tries lines 11 to 13, then 10 to 14 and so forth.

I don’t know exactly how you would calculate indentation with regexes. Currently the code updates some state after each line. And it’s only going up from the current line IIRC.
