[josm-dev] [PATCH] Hack to make TIGER editing easier

[Dave Hansen]

Virtually all of the TIGER data has a tag like

	"tiger:tlid" = "1234:5678"

including nodes.  When I merge nodes, I spend a lot of time combining 
the tags like this:

	"tiger:tlid" = "1234:5678"
	+
	"tiger:tlid" = "33:22"
	=
	"tiger:tlid" = "1234:5678:33:22"

So, here's a quick JOSM hack to do it.  Is there a way I could
generalize this so that other people could do similar things?  Perhaps
in a plugin?
