yecc bug

[Martin Bjorklund]

Here's a small fix to parsetools/include/yeccpre.hrl which creates
better printouts for some parse errors:

95c95
< yecctoken2string({Cat, _, Val}) -> io_lib:format('~w', [Val]);
---
> yecctoken2string({Cat, _, Val}) -> io_lib:format('~p', [Val]);

[also, it looks like this code is duplicated into yeccparser.erl -
that module should probably include yeccpre.hrl instead]


So you don't have to see:

../c_src/reg_proto.x:204 : syntax error before: [115,117,98,115,99,114,101,115]
