Is there a ZSH standard way to collapse a file path to its shortest
representation that would be idempotent per Chapter 14.7?

For example, one might

echo "$filepath" | sed -E "s|$HOME/?|~/|"
echo "$filepath" | sed -E "s|$HOME/?|\$HOME/|"


In order to turn

/home/username/bar/baz → ~/bar/baz
/home/username/bar/baz → $HOME/bar/baz


To achieve this effect.

From the documentation, "14.7 Filename Expansion" has a lot of ways that
paths can be expanded, including...

14.7.2
... the path is checked to see if it has a named directory as its prefix.
If so, then the prefix portion is replaced with a ‘~’ followed by the name
of the directory ....


Is there a standardized way to access this expansion with e.g.
/path/to/somedir → ~SOMEDIR/foo?

I expect this can be implemented manually by parsing the output of "hash
-d" or similar, but I figured it was worth asking if there's an easy
interface to this.

I'm not concerned as much about "14.7.1 Dynamic named directories" but for
completeness it would be neat.
