> Commit 8638aace3fbe01529f33870f469fa60bf5e43ee7
> introduced a bug which will cause byte-recompile-directory to 
> invert the semantics of the byte-compile-ingore-files option.
> 
> To reproduce:
> 
> 1. mkdir /tmp/bug/ && cd /tmp/bug/
> 2. Copy an elisp file which would normally be byte-compiled into 
> that directory
> 3. emacs -Q --batch --eval "(byte-recompile-directory 
> default-directory 0 'force)"
> 
> You should see output similar to:
> 
> Checking /tmp/bug...
> Done (Total of 0 files compiled)
> 
> 
> In general the entire logic of byte-recompile-directory is messy.
> Two ifs without elses, lots of negated predicates, etc. I can see 
> why the mistake was easy to overlook. This could be further 
> refactored to make it easier to read by leveraging when/unless 
> appropriately. Perhaps there's an argument for some abnormal hooks 
> in place of those long chains of ad-hoc predicates, but I'm more 
> interested in fixing the problem now.

> The attached patch fixes it for me.
