Right now, if you try to set a style with a bad value, tmux will
return an error, but it'll set the style to default. This happens
even if the style isn't currently set.
For example:
localhost> tmux show -w
localhost> tmux set pane-border-style bg=BadValue
bad style: bg=BadValue
localhost> tmux show -w
pane-border-style default
localhost> tmux set pane-border-style bg=red
localhost> tmux show -w
pane-border-style bg=red
localhost> tmux set pane-border-style bg=AnotherBadValue
bad style: bg=AnotherBadValue
localhost> tmux show -w
pane-border-style default
I've attached a patch that changes this behavior. If you pass a bad
value, then you still get the error message, but the option isn't set
or changed.
