Re: Dynamic menus

Hi,

I added the support of multiline strings à la Python, as a POC and only 
with double-quotes.

It allow to embed more easily small shell scripts in f.exec or f.dynmenu 
action param, without to quote every encountered ".

f.dynmenu """
cat <<EOF
"$(hostname)" f.title
"*$(date)"    !"daemon xterm"
"Details..."  f.dynmenu "/usr/local/bin/another_menu.sh"
"Shutdown" ("white":"red") !"shutdown -r now"
EOF
"""

What do you think of this?
