This fixes the use case where a directory in the dir stack
doesn't exist anymore, so the keystroke doesn't appear to
do anything.

It will keep trying to switch to the n-est directory in the
stack until it founds an available directory or the dirstack
has no more directories to switch to.

*  Also gfa conflicts with git shortcut

The parsing output for full git log output too slow so it replaced
with last commit show request, wich cause error if repository is empty

This reverts commit 7d298a30.

This conflicts with several tools, including NodeGH [1] and
scm_breeze [2].

Fix pj plugin

The `shwordsplit` option affects all variables and we only need to split
the `$EDITOR` variable. Because of that, using `${=spec}` is a much better
alternative.

- Use `emulate -L zsh` to make all variables local.

- Use `shwordsplit` to interpret `$cmd` spaces correctly.

- Rename `$project` and `$file` variables to the more appropriate `$basedir`
  and `$project`.

- `$PROJECT_PATHS/*` wasn't working correctly. You have to iterate over
  its elements in order to use globbing with it.

- The `$projects:t` line wasn't necessary if we used `compadd`.

- `compadd` better supports destructuring an array with spaces in some
  of its elements.
