Subject: tmux.conf: Use line continuation.
X-Git-Url: https://ruderich.org/simon/gitweb/?a=commitdiff_plain;h=ab9717d6cf1d9b0d1a5a3e2c932f39e8dd561a7f;p=config%2Fdotfiles.git

tmux.conf: Use line continuation.

Also add new script remove-continuation.pl which performs this change.
Older Tmux versions don't support line continuation.

Adapt setup.sh to generate tmux.conf from tmux.conf.in.
