Hello,

Several of our bsd.*.mk files support specifying per-target specific  
variables.  What I'm referring to is the following:

FILES= foo bar
FILESDIR_foo= ...
FILESDIR_bar= ...

PROG= foo
COPTS.foo= ...
CPPFLAGS.foo= ...

Some files currently use a _ separator while others use ., as shown  
above.  Is it there any rationale behind this difference?  If there  
isn't, do you think it's worth to sweep these to unify them all to  
use the same separator?
