EMC fixes to verify, steppers, etc.

EMC folks,

I fixed a problem with the new program verify feature in which some
errors failed to pop up on the display. I also twiddled with the motion
defaults and fixed a problem that some of you may have noticed if you
are running your stepper system near the pulse task limit.

I put a new release on the FTP site, dated 16 June 1999.

And still working on the EMC User's Guide...
