Update of /b/source/CVS/src/libexec/comsat
In directory sun-lamp.cs.berkeley.edu:/f/users/briggs/comsat

Modified Files:
	comsat.c 
Log Message:
Change from bicknell@csugrad.cs.vt.edu and ceharris@csugrad.cs.vt.edu.
This closes an apparent security problem on systems where users have
write access to the mail spool.  Since root actually runs comsat, a
user could link their mail file to a system file that they normally
could not access, and use comsat to view said file.  This fix simply
makes sure that the mail file is a REGular file.
