I could definitely do that.

Sure. I think we already have code that can do that, so I might want to
do a bit of refactoring.

This is where it stops working. On Windows, at least on NT-class
systems, you really do want to use the wide char functions to read the
environment and convert the result to UTF-8, otherwise we're not safe in
the presence of characters that can't be represented in the current
locale. I don't want to lose that capability, after all the trouble we
(you?) went to in the other I/O functions.

apr_filepath_getenv, maybe? (Put it in the apr_filepath namespace
because the value it returns is suitable for input into other apr_file*
functions.)

Bah. We have apr_filepath_merge; there's no need to duplicate that
functionality, is there?
