fix dirh output with reversed $dirnext

[jakalada]

Description

Before:

The order of the variable $dirnext output by the dirh function is reversed.

$ cd Desktop
$ cd a
$ cd b
$ cd c
$ dirh
 4) /Users/jakalada
 3) /Users/jakalada/Desktop
 2) /Users/jakalada/Desktop/a
 1) /Users/jakalada/Desktop/a/b
    /Users/jakalada/Desktop/a/b/c

$ dirh

    /Users/jakalada/Desktop
 1) /Users/jakalada/Desktop/a/b/c
 2) /Users/jakalada/Desktop/a/b
 3) /Users/jakalada/Desktop/a
$ nextd 3                            # select "3) /Users/jakalada/Desktop/a"
$ dirh
 4) /Users/jakalada
 3) /Users/jakalada/Desktop
 2) /Users/jakalada/Desktop/a
 1) /Users/jakalada/Desktop/a/b
    /Users/jakalada/Desktop/a/b/c    # oops! unexpected.

After:

Fixed.

$ dirh
 1) /Users/jakalada
    /Users/jakalada/Desktop
 1) /Users/jakalada/Desktop/a
 2) /Users/jakalada/Desktop/a/b
 3) /Users/jakalada/Desktop/a/b/c
$ nextd 3                             # select "3) /Users/jakalada/Desktop/a/b/c"
$ dirh
 4) /Users/jakalada
 3) /Users/jakalada/Desktop
 2) /Users/jakalada/Desktop/a
 1) /Users/jakalada/Desktop/a/b
    /Users/jakalada/Desktop/a/b/c     # expected!

TODOs:

• Changes to fish usage are reflected in user documentation/manpages.
• Tests have been added for regressions fixed
• User-visible changes noted in CHANGELOG.md

Isn't this working as intended - showing least-to-most recent, rather than a stack?

[jakalada]

nextd has a parameter for specifying the path by number, but it is not working properly.

I added description.

Before:

$ dirh
 1) /Users/jakalada
    /Users/jakalada/Desktop
 1) /Users/jakalada/Desktop/a/b/c
 2) /Users/jakalada/Desktop/a/b
 3) /Users/jakalada/Desktop/a
$ nextd 3                            # select "3) /Users/jakalada/Desktop/a"
$ dirh
 4) /Users/jakalada
 3) /Users/jakalada/Desktop
 2) /Users/jakalada/Desktop/a
 1) /Users/jakalada/Desktop/a/b
    /Users/jakalada/Desktop/a/b/c    # oops! unexpected.

After:

$ dirh
 1) /Users/jakalada
    /Users/jakalada/Desktop
 1) /Users/jakalada/Desktop/a
 2) /Users/jakalada/Desktop/a/b
 3) /Users/jakalada/Desktop/a/b/c
$ nextd 3                             # select "3) /Users/jakalada/Desktop/a/b/c"
$ dirh
 4) /Users/jakalada
 3) /Users/jakalada/Desktop
 2) /Users/jakalada/Desktop/a
 1) /Users/jakalada/Desktop/a/b
    /Users/jakalada/Desktop/a/b/c     # expected!

As it is a display problem, I felt it appropriate to fix dirh.

Merged, thanks!
