This is totally unrelated topic, but how would we do if we want to support
non-contiguous range?

   -L file,a:b,c:d

is ambiguous because file may contain ",".

I guess we could iteratively rsplit(",", 1) the file pattern and try to
parse "from:to" until it fails, meaning that the remaining would be the
file name. Slightly more complicated than it is now, but still doable I

That doesn't sound nice because only reason we've introduced -L was to reliably
split linerange from file pattern. "1:2" looks odd, but is a valid filename on

I'm afraid I don't follow, could you elaborate a bit?

By the way, I worked on this a bit earlier, just after your first email


It seems to be working, but I may have missed something of course.

I meant "1:2,3:4,5:6" could be parsed as either

  file="1:2,3:4" linerange="5:6"


  file="1:2" linerange="3:4,5:6"

because "1:2,3:4" is a valid filename. This would get more complicated if
we want to support other types of linerange specifier seen in git.

Ok, I see. Any separation character (apart from / maybe) would lead to such ambiguities I guess. Maybe we can live without this and specify -L multiple times? I have no better idea at the moment.
