Backwards compatibility. In 2003 when the project started, the humidity
sensor was in common usage (a published design for a sought-after feature
with a number of commercial versions available, especially for weather
stations). There was no way of telling if a humidity design was implemented.
The data fields for the multisensors weren't in use (and right now it's
unique ibuttonlink and even they don't document it fully).
As more designs came out, I moved the the subdirectory model, which at least
visually makes more sense. Changing the behavior for existing code is
unappealing.

Would a commandline switch like "--multisensor" that displayed only
multisensor files be a good compromise?
