Bug in `syscmd'

The documentation for M4 says that `syscmd' does not expand 
to the command's output or error.  But when I run `syscmd', 
if the command gives an error, the error shows up.  This 
differs from documented behavior, so it is a bug.  Test 

syscmd(`cat nonexistant-file')dnl

It should display an ENOENT error message on M4 output.  
This is a bug.
