I didn't know if they used git or hg, and I wasn't necessarily having a go at either. The poster obviously thought that there was less friction to an online edit, so you have to ask yourself why that is?
Perhaps they don't like fiddling about on the command line, their IDE is too klunky, file managment is a pain, their version control interface is convulted, or they are not sitting at their computer with their codebase - who knows!
Either way they appear to find it easier that way.
Or maybe the issue tracking system is a web tool that links to the file in the repository and you could fix it with a click to edit instead of pull,open file,fix,commit,push.
Documentation or fixes to comments in code is an obvious usecase for online edits cross-language.
If you'd really rather do the pull,open,fix,commit,push i would argue that you are too stuck in your own ways.
