Dear All,

 in the current master branch, if the parameter :tangle of a src block is not
a string, tangling fails by throwing  an error when calling `file-name-
directory'  This patch checks if the parameter is a string before calling
`file-name-directory'.

This makes construct such as :tangle (when condition-applies "filename") work
again (as they did a few versions ago…)

Thanks for your time
Best
 Jacopo

Thanks for the patch. It looks good to me (had to run `dos2unix' to apply).

To clarify, it fixes `:tangle (when condition-applies "filename")' when the
condition doesn't apply, such as `(when nil "filename")'.

Regards,

Dos2unix? I'll make sure it doesn't happen again. It might have to do with having sent the patch from Android.

Yes, I will update the commit message and resubmit. Thanks!
