[development] "HEAD" vs. "TRUNK" -- i hereby retract my earlier rants: call it "HEAD".

[Derek Wright]

i was skimming http://drupal.org/node/82257 and noticed some people  
referring to "TRUNK" and others to "HEAD".  this is all my fault. ;)   
furthermore, i'm hereby admitting i was wrong about this.  CVS is  
just internally inconsistent about its own terminology. :(

while it's true that every branch has a head (the end of that  
branch), there really is only one HEAD (all caps), which is the  
special case of the head of the trunk.  there's no such thing as "cvs  
co -r TRUNK", but you *can* do "cvs co -r HEAD".  so, it's confusing  
and lame, but if you mean the trunk, it probably *is* best to just  
refer to it as "HEAD", since that's the special-case "branch" you can  
checkout from (or update to) that CVS uses internally.  if you want  
to talk about the trunk, best to do so without the caps, so as not to  
confuse it with the name of a valid "branch".

my apologies for introducing this inconsistency in our own vocabulary...

thanks,
