[svn-r3336] Purpose:
    Simple twist
Description:
    snapshot used to just use whatever `hostname` returns.  Often it
    is the fully qualified name but sometimes just hostname without the
    domain part.  Inconsistent.
Solution:
    Chopped off any domain part and use just the host name.
    Use the 'cut' command rather than the sed with ncsa.uiuc.edu hardcoded.
    Applied that to runtest too.
Platforms tested:
    Should work.  Will find out if the daily tests still work.
