Fabian Homborg 0072367512 fish_add_path: Don't resolve symlinks
The case for symlinked directories being duplicated a lot isn't there,
but there *is* a usecase for adding the symlink rather than the
target, and that's homebrew.

E.g. homebrew installs ruby into /usr/local/Cellar/ruby/2.7.1_2/bin,
and links to it from /usr/local/opt/ruby/bin. If we add the target, we
would miss updates.

Having path entries that point to the same location isn't a big
problem - it's a path lookup, so it takes a teensy bit longer. The
canonicalization is mainly so paths don't end up duplicated via weird
spelling and so relative paths can be used.

.. _cmd-realpath:
realpath - convert a path to an absolute path without symlinks
==============================================================
Synopsis
--------
::
realpath PATH
Description
-----------
``realpath`` resolves a path to its absolute path.
fish provides a ``realpath`` builtin as a fallback for systems where there is no ``realpath`` command, your OS might provide a version with more features.
If a ``realpath`` command exists, it will be preferred, so if you want to use the builtin you should use ``builtin realpath`` explicitly.
The following options are available:
- ``-s`` or ``--no-symlinks``: Don't resolve symlinks, only make paths absolute, squash multiple slashes and remove trailing slashes.
