Reformat the selection or the whole document, only adjusting whitespace.
What it does:
- remove trailing whitespace
- newline after all { or << in lilypond mode, unless terminated on same line
- same way newline before >> or }
- remove indent for commented lines with more than two comment characters
- never removes existing newlines
- Html, scheme, strings, etc are left alone
What it also could do, but not yet:
- newline before and after many non-postfix commands, such as \set, \override
- at least one blank line between multiline top-level blocks (unless comment)
- wordwrap lines longer than 79 characters
