reentrant lexer: YY_LESS_LINENO taking care of yycolumn

[jannick0]

For a reentrant lexer YY_CURRENT_BUFFER_LVALUE contains as members the current line number, but also the current column number. It would be great if the macro YY_LESS_LINENO could take care of yycolumn, too.
For now I am currently using the snippit below in the .l footer as a workaround which might be a starting point for a patch supposedly to flex.skl:

--- YY_LESS_LINENO_v0.c
+++ YY_LESS_LINENO_v1.c
 #undef YY_LESS_LINENO
 #define  YY_LESS_LINENO(n) \
             do { \
                 int yyl;\
-                for ( yyl = n; yyl < yyleng; ++yyl )\
-                    if ( yytext[yyl] == '\n' )\
-                        --yylineno;\
+                for ( yyl = n; yyl < yyleng; ++yyl ){\
+                    yycolumn--; \
+                    if ( yytext[yyl] == '\n' ){\
+                        --yylineno;yycolumn=0;}\
+                }\
             }while(0)

Thanks,
