more: fix null-pointer dereference

The command allows executing arbitrary shell commands while viewing a file by
entering '!' followed by the command. Entering a command that contains a '%',
'!', or '\' causes a segmentation violation.

The same more(1) function has a problem when not file is specified (cat
/etc/passwd | more) on command line.
