[FRG-73] Issues With Nested Comments

[dynamobi-build]

[reporter="jhyde", created="Fri, 17 Mar 2006 14:44:26 -0500 (GMT-05:00)"] There are miscellaneous bugs with nested multiline comments.

1. This should be valid (if I read the spec correctly), but currently it crashes
   the parser. (It throws an obscure Error.)
   
     /* outer /* inner comment _/ comment */
   
   
2. It should be illegal for a multiline comment to contain a single-line
   comment, like this:
   
     values / multiline contains -- singleline /
     (1)
   
   
3. "_/" without preceding "/" should fail gracefully, but the parser barfs:
   
     values (1 / 2)
