How to force comment/uncomment instead of toggle?

[mgutz]

In most cases toggling comments is what I want. In some cases I want to force uncommented lines to be commented and leave commented lines commented. I imagine something like this

:g/log.debug/CommentaryComment

would change

log.debug('context', JSON.stringify(context))
...
// log.debug('socket.rooms', JSON.stringify(socket.rooms)) 

to this, effectively commenting out all log.debug statements.

// log.debug('context', JSON.stringify(context))
...
//// log.debug('socket.rooms', JSON.stringify(socket.rooms))
