 [https://en.wikipedia.org/wiki/List_of_FTP_commands FTP command] `CWD`? If
 yes, seems an empty `exists()` may be expected to return true as it will
 be checking the current working directory?

 Thanx for looking at this @azaozz .  The point of this ticket is that the
 current behavior of `::exists('')` for the FTP filesytems is different
 than that for the `direct` filesystem.

 And that incongruity could cause problems (not likely for core's use of
 the filesystem classes, but for extenders' uses).
