[Tagging] shop=farm shop=greengrocer

[Bryce Nesbitt]

I'm interested in propsing an icon for "shop=farm", for highlighting 
roadside farm stands (this is a fun travel activity, as such farm stands 
are often not listed in the Yellow pages or conventional maps).

I've thought a single apple is a reasonable symbol for this.

However, the existing greengrocer tag has a single apple in potlatch2 
(no rendering in mapnik or osamarender). What would people think of 
merging the greengrocer and farm tags into one, then using the apple as 
the symbol?

I see a lot of overlap between the two tags.  If there is any 
distinction between the two tags it is usually clear in context: in the 
middle of a city it is more like a "greengrocer" , and out in a rural 
area it is more like a "farm stand".  Many rural farm stands these days 
sell bananas and exotic, so that hardly distinguishes the two.
