I happened to see this in the Solaris man page for `errno':

     The perror() function produces a  message  on  the  standard
     error  output.... 
     The  argument string s is printed, followed by a colon and a
     blank, followed by the message and a NEWLINE character.   If
     s is a null pointer or points to a null string, the colon is
     not printed.

So perhaps this patch to our perror.c is in order?  (The manpage says
only that the colon is not printed; should the blank still be printed?)
