Good to fix phone number in general, one comment on a specific change.

I had a look at this change for this object, https://www.openstreetmap.org/way/1189992346

It is changing "+31 6 30898025; +31 6 55334879" to "+31 6 30898025;+31 6 55334879" so (only) removing the space after the ";"

I do not think that is needed or better.
