lang/{erlang,mono,node}: port+category !ports-readmes

[Constantine A. Murenin]

Dear ports@,

I was adding the counts on the number of packages and categories for 
http://ports.su/ , and during my verification phase, I've noticed 
that the numbers didn't match with the total number of pages.

Investigation revealed that out of 8618 packages and 68 categories 
from the recent amd64 snapshot (according to the sqlports-compact 
package), there are 3 strings that are present in both namespaces:  
lang/erlang, lang/mono and lang/node.

This results in the packages being overwritten by the categories 
(since the categories are processed after the ports), thus causing 
for a total of 3 packages to be missing from ports-readmes.  
The original in-tree /usr/ports/databases/ports-readmes is affected, 
too, not just my ports.su fork.  
I'm not sure whether http://ports.su/databases/ports-readmes-dancer is affected.

(For what it is worth, 3 is less than some 1632 packages that are 
missing from openports.se, but it is still 3 packages too many.)

Are the namespaces expected to collide like that, and should be 
addressed within ports-readmes, or is this something that could 
be addressed on the http://ports.su/databases/sqlports level?

Cheers,
Constantine.
