bug#24428: 25.1; batch-byte-recompile-directory no longer works as it should

[John Wiegley]

It seems that `batch-byte-recompile-directory' now doubles the argument
somehow.  I was unable to track down the commit where this was introduced, but
this is happening in a Makefile that worked for years until recently:

--8<---------------cut here---------------start------------->8---
10:42:49 Vulcan:~/.emacs.d $ emacs -Q -batch -L . --eval 
'(batch-byte-recompile-directory 0)' lib
Checking /Users/johnw/.emacs.d/lib/lib...
Error: Opening directory: no such file or directory, 
/Users/johnw/.emacs.d/lib/lib
Done (Total of 0 files compiled)
--8<---------------cut here---------------end--------------->8---

Notice the 'lib/lib' there.  Using `byte-recompile-directory' interactively
from within a running Emacs works fine, however.
