Kurtis Rader 9d2b53450a limit size of cd history to 25 directories
The existing implementation grows the $dirprev array without bounds. Besides
causing what would appear to be a memory leak it also makes the nextd and
prevd commands more expensive than they need to be. It also makes it harder to
create a useful "menu" cd command.

In addition to implementing a reasonable limit on the size of the $dirprev
array I've reformatted the code using fish_indent.

Update the documentation to include mentions of the $dirprev and $dirnext
variables as well as the limit on how much directory history is kept.
