Resolves an issue cause by a syntax error and a removed executable bit
introduced by dracula/tmux#153.
The syntax/permissions issue stops the plugin from running properly when
I ran into the issue earlier today.
The missing executable bit is likely what's causing dracula/tmux#178
given that `man bash` has the following excerpt:
> If a command is found but is not executable, the return status is 126.
