Subject: streamDevice redirection-to-records & PVs that start with a number

FYI,

I discovered that streamDevice's redirection-to-records feature fails if 
the name of the destination PV starts with a number:

   https://github.com/paulscherrerinstitute/StreamDevice/issues/20

There have been multiple times in the past where streamDevice support 
that used the redirection-to-records feature worked in my development 
IOC but didn't work when I deployed it to a beamline.  This problem 
wasn't discovered then because eliminating redirection from the support 
was easier than troubleshooting the redirection failure.

This problem is very likely to occur at the APS.  The PV prefix for 
development IOCs is often the developer's initials.  The beamlines are 
numbered and the PV prefix for beamline IOCs usually begins with the 
beamline number.

I hope this saves someone else a little frustration.

Kevin
