Re: -C -like option to change CWD on startup

thanks for the interesting example. I would want to note two other programs that follow -C option convention, namely tar and env. The second can be even used to workaround the problem, i.e.:

env -C ~/github zsh -c 'some commands'

but still, a dedicated option would be good.

You can do this:

zsh-in-dir() ( builtin cd -q -- "$1" && builtin exec zsh "${@:2}" )

This forks and execs once, the same as if there was a native `-C dir` option.

Note that your original code has the same performance thanks to an
optimization in zsh. The second fork is elided.
