pardes NEWFILE in a pane forwards even when its directory is missing, and Save makes the directories

fs.md said FILE must already exist, while `pardes new.txt` in fact
forwarded, making a pane named for it that Save creates. With a missing
directory (`pardes notes/new.txt`) the launch gave up forwarding and started
a nested editor inside the pane. Now the name is made absolute as written
and forwarded the same way. A name written to a pane's name file that goes
into a directory not there has its Save make the directories, as Config's
pane does. A Save <path> into a missing directory still fails ENOENT. The
Forwarding section now says what a new FILE does. fs.py launches one into a
missing directory and saves it.
