(uxnasm) only ignore [ or ] if it is a whole token
Currently, tokens beginning with a [ or ] character are completely
ignored, which forbids a macro from beginning with these characters.
Specifically, a macro can be declared eg. as `%[x { ... }` but cannot be
dereferenced as `[x`.
This patch only ignores these tokens if they have a length of 1;
otherwise the switch falls through to the default case.
