[Keepright-talk] restriction:conditional, only_u_turn and multiple from/to members

[<eas...@po...>]

Hi,

Thanks for your work on keepright!

I noticed that restrictions like this one:
https://www.openstreetmap.org/relation/13297182 (version #1)
where the restriction is conditional like:
restriction:conditional=only_straight_on @ (Mo-Sa 05:00-20:00)
are reported to have an 'unknown type'.
However, the the wiki suggests using them:
https://wiki.openstreetmap.org/wiki/Relation:restriction
and they are used also rather frequently, so there are lots
of false positives for this check.
There are even some that are restricted to a certain vehicle
and provide another condition like restriction:hgv:conditional.

Another type of false positives I found are no_entry restrictions
with multiple from members which is allowed according to the wiki.
For example this one: https://www.openstreetmap.org/relation/13924242
(version #1). Also restrictions no_exit restrictions with multiple
to members are allowed.

One more: The wiki includes the restriction type 'only_u_turn' which
is also reported by keepright, for example here:
https://www.openstreetmap.org/relation/13268830 (version #1)

Btw do you keep track of false positives reported via the keepright
UI? I wasn't sure wether I should report this here or via the
tool.

Cheers
