make -C weirdness

Hi,

Long time ago I wrote 2 simple aliases to my .cshrc:

search_key      make -C /usr/ports/ search key='!*' display=name,path,info
search_name     make -C /usr/ports/ search name='!*' display=port,path,info

it works fine starting from 7-CURRENT  IIRC. 
Today 	I tried to find some (existing) port and can't, for example:
[tiger_at_laptop]:/>make -C /usr/ports/ search name=teeworlds
display=name,path,info
[tiger_at_laptop]:/>
but
[tiger_at_laptop]:/>cd /usr/ports/
[tiger_at_laptop]:/usr/ports>make search name=teeworlds display=name,path,info
Port:   teeworlds-0.6.4_4 
Path:   /usr/ports/games/teeworlds 
Info:   Platform game featuring buggers equipped with
weapons

it is  on 12.0-CURRENT r324493
I missed something or it is a bug?
