I think I have enough to make my first try at a conservative (but not 8.3)
  file name constraint for my Revolution apps and libraries (and stacks and 
files in general).

Dar's very conservative file name syntax for Revolution:
      The file name consists of
      up to 25 alphanumeric-and-underline chars,
      a dot, and three alphanumeric chars.
      The letters may be upper and lower case,
      but the case may be lost along the way.

I don't know how to write "up to 25" in regex, so I can't impress Ken Ray 
by putting it in regex.

Is this too conservative?  Does it have a hole?  (Are there cases where I 
need at least one char before the dot?)
