The docstring for ediff-regions-linewise says:

  "Run Ediff on a pair of regions in specified buffers.
Regions \(i.e., point and mark\) are assumed to be set in advance except
for the second region in the case both regions are from the same buffer.
In such a case the user is asked to interactively establish the second

I find that, even if I mark regions in both buffers before calling
ediff-regions-linewise, I am still asked to interactively set the
regions.  This seems to be new behaviour which I couldn't find
documented in NEWS.  Is this intended behaviour (its new to me -- Emacs
used to rely on me setting the regions before calling the defun.)?

(I tested this by making two files, ~/f1 and ~/f2 and marking a region
in each buffer before calling ediff-regions-linewise)

Thanks, Stephen
