ls broken in shell.

[Chris Johns]

Hello,

It looks like 'ls' is broken in the shell. On sparc/sis running fileio, 
selecting 's' for shell, logging in and then 'ls' exits the simulator. I 
saw this with mksh and assumed something was not working with mksh 
however this now looks like something in 'ls'. With mksh I traced the 
fault to the heap free call in mksh that failed on the heap check. I 
have not looked into the fileio failure.
