Subject: zsh/rc: Use exec when automatically starting screen.
X-Git-Url: https://ruderich.org/simon/gitweb/?a=commitdiff_plain;h=81fe12757189bc144a22271f5bc669dd98ea2c37;p=config%2Fdotfiles.git

zsh/rc: Use exec when automatically starting screen.

This needs one less shell on the server and makes it faster to detach
(no need to exit the first shell).
