I can look into that as a generally useful addition.

For this particular case though, I don't know if it's completely
necessary: The functions that are bound to keys here silently do nothing
if there's only one tab and the bindings don't get added if there are
other bindings for those keys, so as far as I can tell, it shouldn't
really make a difference whether or not the bindings are active when the
tab bar isn't visible.

It is entirely possible I'm missing something though and it certainly
does seem "cleaner" to remove the key bindings when they don't need to
be there.
