[PATCH v2 3/5] check-docs: really look at the documented commands again

From: Johannes Schindelin <johannes.schindelin@gmx.de>

As part of the `check-docs` target, we verify that commands that are documented are actually in the current list of commands to be built.

However, this logic broke in 5fafce0b78 (check-docs: get documented command list from Makefile, 2012-08-08), when we tried to make the logic safer by not looking at the files in the worktree, but at the list of files to be generated in `Documentation/Makefile`. While this was the right thing to do, it failed to accommodate for the fact that `make -C Documentation/ print-man1`, unlike `ls Documentation/*.txt`, would *not* print lines starting with the prefix `Documentation/`.

At long last, let's fix this.

Note: This went undetected due to a funny side effect of the
`ALL_PROGRAMS` variable starting with a space. That space, together with
the extra space we inserted before `$(ALL_PROGRAMS)` in the

	case " $(ALL_PROGRAMS)" in
	*" $$cmd ")
		[...]

construct, is responsible that this case arm is used when `cmd` is empty (which was clearly not intended to be the case).
