Actually, `SKIP_DASHED_BUILT_INS` does not _only_ have an impact on `make
install`:

	$ rm git-add.exe && make
	    BUILTIN git-add.exe
	    BUILTIN all
	    SUBDIR git-gui
	    SUBDIR gitk-git
	    SUBDIR templates

	$ rm git-add.exe && make SKIP_DASHED_BUILT_INS=1
	    BUILTIN all
	    SUBDIR git-gui
	    SUBDIR gitk-git
	    SUBDIR templates

See how `git-add.exe` is linked in the first, but not in the second run?

So the difference 3/3 has is that those hard-linked executables are not
even generated. Now, _technically_ this should not result in any change
because we run the test suite without `--with-dashes`.

Practically, it _does_ make a difference, though, as `bin-wrappers/git`
_specifically_ sets `GIT_EXEC_PATH` to the top-level directory, i.e.
`git-add.exe` _would_ be found if any core Git command that is still
implemented as a script called `git-add`.

Therefore, 3/3 makes sure that we really, really, really do not use those
dashed invocations ourselves.

Ciao,
Dscho
