entrance is important, but mapping duplicate shops causes multiple problems :
* inability to find out "how many Lidls are there"
* polluting search results in GPS devices and similar
* requiring all the detail to be mapped and maintained twice (opening hours, contact info etc) - and it is pretty much guaranteed to get out of sync. here the two shops already have quite a different info tagged on them.

discussing this on irc, it was suggested to use entrance node + highway=footway or highway=corridor instead. not only this would remove the duplication problems, it would also allow GPS devices to route to the correct street to find the entrance.

i tried to map it this way, using highway=footway (corridor does not seem to be too popular still, not sure whether anything uses it in routing).
please let me know what you think - if the approach seems reasonable, please help to remove shop duplication this way.

keeping the note open for further discussion/comments.
