Formatting exceptions

[vpax]

It seems likely that we're going to need some way of flagging "heh zeek-script the following is ok, leave it be". Maybe &sic :-P. I don't have a suggestion for how to do this without the flag itself looking clunky, though.

clang-format uses magic comments for this.

This is great, yeah. # sic could apply to the thing on the next line when it's a standalone comment, and to the preceding thing when it's tucked on at the end of a line. And a more formal # zeek-format skip|on|off could take care of larger stuff, or those who want to be explicit.

This also foreshadows linting a little bit ... seems to me all linters take some form of comment-based hinting.
