Open file on line/col

[dsseng]

Describe your feature request

Helix should parse file open commands and params like src/main.rs:15:8 for opening files on specific place. This can be convenient to fix errors reported by tools, since user won't need to find that place manually, :o /path/to/file:line:col would be enough to get right to the needed file location.

URI's are probably great thing to handle as well, maybe in another PR to avoid chaos.

I can take any of those two once it's considered to be a useful feature.

#445 is a take on this.

[dsseng]

Oh, great! Definitely a useful feature.

Ah, I realized someone else wanted the same feature as me. I will gladly push the PR. There is just bug left such that if multiple file/pos is specified, only the first one would work, the rest does not work, not quite sure how to fix it yet.

I can take a look at the code if you want and when I have time.
