Even this can be trivially solved for a traditional bmaked port.  Just 
import the vendor sources in a directory structure like this:

	tcl
		Makefile		locally written bmakefile
		tcl_subdir1
			Makefile	locally written bmakefile
		tcl_subdir2
			Makefile	locally written bmakefile
		vendor
			complete tcl sources on vendor branch.

This way any FreeBSD changes to the actual tcl source files happen in 
tcl/vendor/.../foo.c and diffs are trivially generated.  Makefiles in the 
vendor branch are completely ignored by our build process but are kept 
around to make new imports easier.

The local build religion stuff which the tcl maintainers are not 
interested is kept completely separate.  Each bmakefile has a VPATH which 
allows it to find the sources from the vendor branch.
