Also display a status: (From `git-show` manpage)
```
"G" for a good (valid) signature,
"B" for a bad signature,
"U" for a good signature with unknown validity,
"X" for a good signature that has expired,
"Y" for a good signature made by an expired key,
"R" for a good signature made by a revoked key,
"E" if the signature cannot be checked (e.g. missing key) and
"N" for no signature
```
As under OSX the -p flag does not exist, it seems safer to just use
`mktemp -d` and create the worktree under that directory.
This just has the disadvantage of one more dir to display in the `PWD`.
On system where my dotfiles are only partially installed (e.g. only
the shell) for the environment variables defined in the zprofile to take
affect, every terminal instance needs to execute zsh a login-shell.
This lead to numerous instances of the ssh-agent that were not killed
when exiting the shell. As I still need the correct env-vars like
SSH_AGENT_PID in every shell I cannot just pgrep and execute the agent
respectively.
This adds a zlogout that kills the agent spawned in the current shell.
It also stops `exec`ing `startx` as then the zlogout is not read.
If a command is normally executed CMD_ON_ENTER is reseted to `ls`.
Otherwise problems can occur when for example switching the directory to
a non-repo when CMD_ON_ENTER contains `gs`.
Disable the option as the search stops taking any input as soon as there
are no search results left. When typing a word fast but making a typo
this is very annoying. Zathura will stop then the search in the middle
of the word and take all remaining characters that are still typed as
commands.
(Maybe create a PR in upstream?)
