Subject: bitkeeper revision 1.1159.223.17 (41f2c67c7vKsSLIzqLuYY24HOjsC5w)

Description: Use vars for complex programs
It's generally standard to call complex programs indirectly thru make
variables.  This allows them to be replaced easily with alternative
versions, without editting each makefile.
Additionally, this patch makes use of $(pkgdocdir) in docs/Makefile.
