Don't use %{%}. They are used to indicate a sequence that doesn't move
the cursor, such as a colour escape sequence. Also, $() is recommended
over ``, but in any case jobs doesn't work in a subshell. A possible
approach would be to put something in precmd (a function run before each
prompt) like this:
function precmd {
if jobs % >& /dev/null; then
psvar=("*")
else
psvar=("")
fi
}
And then put "%1v" in your prompt, for example:
PROMPT="%1v> "
and this will put a * in your prompt if there are any background jobs.
You can substitute any other sequence.
I think I might start using this myself.
