In further consideration in the thinking room, two other ideas presented
themselves:

1) Create files with a leading '-' character to flag deletion.

2) Create a !deleteme directory containing files or directories that
should be deleted.  (Although empty directories can be automatically
detected and are not really an issue)

I like either of these better than the zero-length file because it
will be obvious from simple directory scanning when a file needs to
be deleted.

I'm thinking that the leading '-' is the easiest to implement since
it is stateless.
