False positive error condition parsing VM_global_library.vm

           Summary: False positive error condition parsing

This bug is actually against 1.3 RC1, but there is no Version listing for that
in the Bugzilla config.

The initial parsing of the global Velocimacro library is incorrectly indicating
an error when context variables which are not passed in as arguments to a macro
are used when calling one macro within the body of another.  Confusing, eh?  I
assume that this could be worked around by putting double quotes around the
supposedly non-existent arguments to the invoked macro, but was wondering if
this was a bug.  Included is a sample problem case and some log output.

>From VM_global_library.vm:

#macro(linkedLoginName $acl $user)
 #linkIf($user.isEditableBy($acl) $currentDomain.getProjectPageURL("UserEdit",
"userID=$user.getID()") $user.getLoginName()) 
#end

#macro(linkIf $condition $link $text)
 #if ($condition) <a href="$link">$text</a> #else $text #end
#end
