I think it would be useful if the URLs in the version control output pane could be clickable.

Many git servers put the PR opening URL to the output which is useful in many cases if the user could immediately click on it. Also the first gerrit push (which creates the gerrit ticket) adds the gerrit url to the output.

As I seen from the code the external commands output processing is done generally (not just for the version control but for compilation as well). It might be useful to implement it generally (for e.g. I have seen URLs in  CMake  build failures).
