bad buf_getbyte patch

[David Horwitt]

I created a workaround/fix for my bad buf_getbyte problem:

*** svr-chansession.c   2005-01-11 13:14:54.000000000 -0800
--- svr-chansession.c.orig      2005-01-03 01:24:04.000000000 -0800
***************
*** 439,445 ****

         if (len == 0) {
                 TRACE(("leave get_termmodes: empty terminal modes string"))
-               return;
         }

         while (((opcode = buf_getbyte(ses.payload)) != 0x00) && opcode <= 159) {
--- 439,444 ----

This seems to work OK w/out ill effects; the TRACE message implies that the return that I added may have
been intended all along.

Cheers,
