slow emacs colorization

[DanGrayson]

A line like this can make emacs spin almost for ever as it tries to colorize it, if the buffer is in M2-mode:

/// asldkfj sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf asld/ sdlkjasdf

Do you know what's causing this? Is it bad regex for /// ... ///?

[DanGrayson]

No, that was a long time ago. Is it still true?

[mahrud]

It seemed to crash emacs when I tried it just now.

Is this still an issue? ///-delimited strings haven't been highlighted since #31.
