(Bibliography/Syntax) Allow ['] in the story title
The ['] substitution is needed for titles like "Gone Fishin[']", with apostrophes outside of words. I7 now forbids all substitutions in bibliographic text, for good reason, but this one could be treated specially.
See discussion at http://inform7.com/mantis/view.php?id=58
Even having the apostrophe considered an actual apostrophe and not a double quote would help. I could imagine a trailing apostrophe is used more often than double quotes.
['] shouldn't be thought of as a substitution, just an escaped character. All printable characters should be allowable in bibliographic text, though some may need to be escape in the source code (and others in the <iFiction>.)

The apostrophe wouldn't be the only one. The double quote as well. And the square brackets themselves, most likely.
