/etc/make.conf oddity (?)

Hi,

today I discovered small issue in /etc/make.conf. I am building my custom 
kernel, config file for one machine is FOX.

I put KERNCONF="FOX" into my /etc/make.conf, make buildkernel in /usr/src 
tells ERROR: Missing kernel configuration file(s) (FOX).

If I change it into KERNCONF=FOX, no error message and build works as if 
command make buildkernel KERNCONF=FOX were given.

My understanding was variable values should be enclosed in quotes, did I 
missread or missinterpret something?

Even if it is no real issue (read: could not find simple workaround), I would 
like to know if it's me or not.

Regards,
Milan
