Line-ending bug on Mac

[Nils Svangard <nils.svangard@...>]

Hello,

I'm not sure if this has been covered already but I've found a bug in 
Lua 4.0's lexer, dealing with line-endings under mac. If the file is 
saved with mac-endings ('\r') comments does not work, but after 
modifying llex.c::luaX_lex alittle, this works.

My changes:

case ' ': case '\t':
next(LS);
continue;

case '\r':
inclinenumber(LS);
		
if (LS->current == '\n')
	next(LS); // Don't count lines twice on Windows.
continue;

case '-':
next(LS);
if (LS->current != '-') return '-';
do { next(LS); } while (LS->current != '\n'
	&& LS->current != '\r' // End comment on mac's as well, but 
increases linecount twice on windows?
	&& LS->current != EOZ);
continue;

Cheers,
