  You're right.  The documentation is wrong
here.  Any place that takes a project-id also
accepts a directory.

Example:
alias system : ../boost-git/libs/system/build ;

I've updated the documentation and also
fixed a few other errors.

- The order of checking is target-name, then
  file-name, then project-id, then directory-name,
  not project-id, then target-name as the documentation
  implies.

The implementation actually supports
(project-id | directory-name) "//" target-id
However, I've left this extra generality
undocumented for now, as I've never seen
any need for it outside of Boost.Build
internals.
