which allows formats to be expanded. Any styles without a '#{' are still
validated when they are set but any with a '#{' are not. Formats are not
expanded usefully in many cases yet, that will be changed later.
To make this work, a few other changes:
- set-option -a with a style option automatically appends a ",".
- OSC 10 and 11 don't set the window-style option anymore, instead the
fg and bg are stored in the pane struct and act as the defaults that
can be overridden by window-style.
- status-fg and -bg now override status-style instead of trying to keep
them in sync.
