The pager `less` coredumps when CTRL+4 are being pressed while viewing a standard text file.
>How-To-Repeat:
        

$ less sometextfile.txt
(press CTRL + 4)

Here's a backtrace from a `less` compiled with -g debug symbols: #0 0x400d95d7 in _thread_sys_read ()
#1 0xba7b in iread (fd=4, buf=0xcfbfd82b "", len 1)

    at /usr/src/usr.bin/less/os.c:119

#2  0xdfb0 in getchr () at /usr/src/usr.bin/less/ttyin.c:95
#3  0x5625 in getcc () at /usr/src/usr.bin/less/command.c:539
#4  0x5908 in commands () at /usr/src/usr.bin/less/command.c:700
#5  0x1b8c in main (argc=-1, argv=0xcfbfd8d0)

    at /usr/src/usr.bin/less/main.c:258

`more` is affected, too.
