Hi!
Since tmux supports chaining commands via \; already, I find it a pity
tmux cannot handle any sort of line continuation as far as I can see.
The patch below implements this feature: lines ending with a single
backslash will trigger the next line to be read in also. Thus, it's
possible to split up big commands over several lines, like this:
# paste latest cutbuffer to sprunge
bind P run-shell \
"tmux set-b $(tmux sa - | curl -F 'sprunge=<-' http://sprunge.us) && \
tmux display-message 'sprunge: upload sucessful!'"
If there's something fishy with the patch, please tell me and I'll
correct it.
