Documentation
Specific allout-prefix leading strings per major modes.
Use this if the mode's comment-start string isn't what you
prefer, or if the mode lacks a comment-start string. See
allout-use-mode-specific-leader for more details.
If you're constructing a string that will comment-out outline structuring so it can be included in program code, append an extra character, like an "_" underscore, to distinguish the lead string from regular comments that start at the beginning-of-line.
