* Prevent off-by-one error on comments on newly appended lines
There was a bug in CutDiffAroundLine whereby if a file without a terminal new line
has a patch which appends lines to it and a comment is placed on one of those lines
the comment diff will be a line out of place.
This fixes CutDiffAroundLine to simply ignore the missing terminal newline - however,
we should really improve this rendering to add a marker to say that there was a
previously missing terminal newline.

* CutDiffAroundLine makes the incorrect assumption that `---` and `+++` always represent part of the header of a diff.
This PR adds a flag to its parsing to prevent this problem and adds a streaming parsing technique to CutDiffAroundLine using an io.pipe instead of just sending data to an unbounded buffer.

* Handle unquoted comment patch files
When making comment patches unfortunately the patch does not always quote the filename
This makes the diff --git header ambiguous again.
This PR finally adds handling for ambiguity in to parse patch

* Add in testing for no error
There is no way currently for CutDiffAroundLine in this test to cause an
error however, it should still be tested.
