Don't set auto_name_dirs because it messes up prompts

[mcornella]

Quick test:

Run in order:

PROMPT="%~ $ "
unsetopt auto_name_dirs
mkdir longnameddirectory
cd longnameddirectory
dir="$PWD"

afterwards, run:

setopt auto_name_dirs
dir="$PWD"

Which should look like this:

> PROMPT="%~ $ "
~ $ unsetopt auto_name_dirs
~ $ mkdir longnameddirectory
~ $ cd longnameddirectory
~/longnameddirectory $ dir="$PWD"
~/longnameddirectory $ # prompt doesn't change
~/longnameddirectory $ setopt auto_name_dirs
~/longnameddirectory $ dir="$PWD"
~dir $ # prompt now uses ~dir instead

From http://zsh.sourceforge.net/Doc/Release/Options.html#Completion-4

AUTO_NAME_DIRS
Any parameter that is set to the absolute name of a directory immediately
becomes a name for that directory, that will be used by the ‘%’ and
related prompt sequences, and will be available when completion is performed
on a word starting with ‘’.
(Otherwise, the parameter must be used in the form ‘~param’ first.)

+1 -- (the AUTO_NAME_DIRS + rvm latest also breaks switching to same directory on new tab in OS X Terminal.app)

[mcornella]

@red56: what breaks switching, this PR or the auto_name_dirs option?

[timdiggins]

@mcornella the auto_name_dirs (+ rvm, in rvm-managed dir) breaks switching (because it's trying to switch from ~RVM_PROJECT_PATH)

[mcornella]

Ok, so this PR fixes that. Thank you for noticing and commenting here.
Hopefully updating oh-my-zsh fixes everything, now that it's merged.

Cheers!

@mcornella yes just verified that this PR fixes that. Thanks for fixing!

[clarkewd]

i think this was also the cause of #3238

Thanks for finding and fixing this! :)

[mcornella]

Indeed it was, @clarkewd, as I explained in the issue in rvm's repo: rvm/rvm#3091 (comment).
