rename: allow renaming in subdirectories

Earlier the rename(1) considered path as possible string to be renamed,
could lead to an issue with none existing destination.  See below for
demonstration of this issue.  After this change all directory elements
are ignored when the match finding happens.

$ cd $(mktemp -d)
$ mkdir aa ab
$ touch a{a,b}/aa
$ rename -v a x */aa
rename: aa/aa: rename to xa/aa failed: No such file or directory

destination are the same location.

Add separate functions to different functionality, and add a function for
the stuff that is in common for both.
