I just did some testing on Windows, and with an @file node Leo acts as if
the os.path functions expanduser() and expandvars() are applied, as well as
the abspath() that would be expected (and probably realpath() but I didn't
check that). This means that you can set an environmental variable, say
VAR, and use it in the path expression as $VAR. I didn't find any
variables that seem to have been added by Leo.
I didn't find where in LeoPyRef.leo this all happens.
