Distinguish temporary and permanent comments

[jeremypw]

Problem

Comments in code may serve more than one purpose:

• Informative comments in addition to the code
• Code commented out for development purposes

It would be useful to distinguish the two so that the latter can be quickly found and removed from a final PR.

At present, <Ctrl>M places // at the start of the text (indented if required) and so it is indistinguishable from an informative comment.

Proposal

When toggling comment on code lines with <Ctrl>M the line is commented out with (e.g. //~) at the very start of the line. Informative comments can then use // or /*. Moreover a search for //~ will find the temporarily commented out code quickly.

Prior Art

Geany uses //~ at the start of the line for toggled comments.
