Clean up the help a bit, removing unimplemented options.

 That's an upper case o, not the number zero.
 If filename is a dash (-) then standard input is used.

                        optimize concatenated strings if they are parenthesized

   foldtabs             Tabs can't be copy-pasted, so they aren't optimized by
                        default. But with support from the viewer, they can be
                        folded too and make it to the uploaded source. This
                        option overrides that check, enabling optimization of
                        strings with tabs. The resulting source isn't guaranteed
                        to be copy-paste-able to a different script, though.
-  * allowcescapes      Enables use of \r, \b, \xNN, \NNN, etc.
-  * enableswitch       Enables Firestorm-compatible switch statements
-                       (not recommended)
-  * lazylists          Enables Firestorm-compatible list syntax, e.g.
-                       mylist[3] = 5; v = (float)mylist[2]; (needs to know the
-                       type to work). Works better with extendedtypecast.
 
 Note that the optimizer doesn't reorder expressions to fold constants. This
 means that e.g. a + 3 + 5 is not optimized to a + 8; however a + (3 + 5) is.
