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. Fixes 2836

\section prevd prevd - move backward through directory history

\subsection prevd-description Description
|
|
|
|
`prevd` moves backwards `POS` positions in the history of visited directories; if the beginning of the history has been hit, a warning is printed.
|
|
|
|
If the `-l` or `--list` flag is specified, the current history is also displayed.
|
|
|
|
Note that the `cd` command limits directory history to the 25 most recently visited directories. The history is stored in the `$dirprev` and `$dirnext` variables which this command manipulates.
