It should not be a blacklist but a whitelist. Most tags make
absolutely no sense with a ; in them. Today its highway
tomorrow its landuse, maxspeed, bridge, tunnel, width, height
building etc which get combined.

The very easy fix is to refuse a merge/combine when there are
different tag values on the 2 segments with a popup. The user
then can cleanup by deleting the tags on one of the segments
and then join. (This is the proceedure i use with josm aswell
as its much quicker than to go through a lenghthy list of 
multiple choices)

The more advanced solution (But probably a lot more confusing for
the user) would be some multiple-choice like in josm.

I'd prefer the first solution. Still everything is possible
but its hard to get it wrong.
