[filebuf.virtuals] Missing const-qualifiers in specification of overflow/underflow.

[keinflue]

[filebuf.virtuals] contains the following code snippet for the specification of overflow:

charT* b = pbase();
charT* p = pptr();
charT* end;
char   xbuf[XSIZE];
char*  xbuf_end;
codecvt_base::result r =
  a_codecvt.out(state, b, p, end, xbuf, xbuf+XSIZE, xbuf_end);

This is missing a const on end because out takes the argument as const charT*&.

Similarly the specification of underflow contains:

char   extern_buf[XSIZE];
char*  extern_end;
charT  intern_buf[ISIZE];
charT* intern_end;
codecvt_base::result r =
  a_codecvt.in(state, extern_buf, extern_buf+XSIZE, extern_end,
               intern_buf, intern_buf+ISIZE, intern_end);

where a const is missing on extern_end.

I am not sure this can be handled as editorial, but at least the intention here seems obvious to me.

Looks quite editorial to me.
