Query about path taxonomy

[mosullivan93]

Hi there,

I quite like your write up on paths but I had a question about one part. Admittedly I didn't read everything as I was most interested in the part about the stem of a filename. So apologies if I've missed the answer.

Regarding the fourth example seen below (leaf(foo.txt) -> foo), this seems to be at odds with the surrounding text, and is actually also seen in the stem section (stem(foo.txt) -> foo). What do you reckon?

Lines 176 to 182 in 7597b41

	```
	leaf(/foo/bar) -> bar
	leaf(/foo/bar.txt) -> bar.txt
	leaf(foo) -> foo
	leaf(foo.txt) -> foo
	leaf(/foo/bar/) -> bar
	```

Thanks,
Mitch
