Another two bugs.
Lines 70-73:
if(!c || !isspace(msg[1]))
sout("%s", msg);
else {
if(msg[1])
If line 73 is executed, isspace(msg[1]) is true. So it can't be equal
to '\0'. Therefore, condition `msg[1]` is always true.

When you type
:a<tab>bcd
line 97
sout("%c %s", c, msg);
will send "a bcd" (tab replaced by space) to server.
