Fabian Boehm 38b24c2325 docs: Use :doc: role when linking to commands
This makes it so we link to the very top of the document instead of a
special anchor we manually include.

So clicking e.g. :doc:`string <cmds/string>` will link you to
cmds/string.html instead of cmds/string.html#cmd-string.

I would love to have a way to say "this document from the root of the
document path", but that doesn't appear to work, I tried
`/cmds/string`.

So we'll just have to use cmds/string in normal documents and plain
`string` from other commands.

.. _cmd-cd:
cd - change directory
=====================
Synopsis
--------
.. synopsis::
cd [DIRECTORY]
Description
-----------
``cd`` changes the current working directory.
If *DIRECTORY* is given, it will become the new directory. If no parameter is given, the :envvar:`HOME` environment variable will be used.
If *DIRECTORY* is a relative path, all the paths in the :envvar:`CDPATH` will be tried as prefixes for it, in addition to :envvar:`PWD`.
It is recommended to keep **.** as the first element of :envvar:`CDPATH`, or :envvar:`PWD` will be tried last.
Fish will also try to change directory if given a command that looks like a directory (starting with **.**, **/** or **~**, or ending with **/**), without explicitly requiring **cd**.
Fish also ships a wrapper function around the builtin **cd** that understands ``cd -`` as changing to the previous directory.
See also :doc:`prevd <prevd>`.
This wrapper function maintains a history of the 25 most recently visited directories in the ``$dirprev`` and ``$dirnext`` global variables.
If you make those universal variables your **cd** history is shared among all fish instances.
As a special case, ``cd .`` is equivalent to ``cd $PWD``, which is useful in cases where a mountpoint has been recycled or a directory has been removed and recreated.
The **--help** or **-h** option displays help about using this command, and does not change the directory.
Examples
--------
::
cd
# changes the working directory to your home directory.
cd /usr/src/fish-shell
# changes the working directory to /usr/src/fish-shell
