Some known bugs that can be described concisely.
(See also POSSIBLE BUGS in todo-small.txt.)

------------------------------------------------------------

 - It doesn't seem to issue a #line directive for the leading block of
embedded C. This might have been intentional, but seems wrong to me.

 - It should warn if an empty character set (which can never be
matched) appears in a production.

 - If you do "[ sticky { foo } ]" where foo is otherwise unreferenced,
you'll be told that foo is both unused and undefined. This is
needlessly confusing. (May be true with "lexeme" also.)

 - Building parsers from files with dashes in their names seems to
result in uncompilable output.

 - There's a "line numbers path" setting, that I didn't know about
until I just found it. But unlike "parser file name", you can't put
'#' in it to expand to the basename of the file.

 - If AG crashes badly, it calls bailOut(). In the windows version,
this pops up a dialog box, which is fine for the GUI version. But it's
also true for agcl.exe, and I doubt this is really desirable.
