With all those new "if"s, "but"s, "otherwise"s, "when"s, and "except"s,
I have a feeling that the current way to say

   If .... ends with a slash, then ... only directories... The trailing
   slash is removed for the purpose of the remaining rules.

is still the best way to go forward. I do understand that this is a
rather technical way to explain things than a colloquial one, but it
also does remove a lot of conditionals and, therefore, mental burden.
