Subject: 24.3.90; ediff-buffers fails when navigating differences

[Message part 1 (text/plain, inline)]

Loaded shell script "stuff.sh" into lower buffer window and "stuff.sh~"
into uppper buffer window (files attached). Then entered command
"ediff-buffers". So far, so good. Then I press the "n" key to navigate
to first diff. This fails with a "Wrong type argument" error message
appearing in the *Messages* buffer window (see Recent Messages, below, for
full text of error message). If the files contain multiple diff 
sections, the *Messages* buffer window will contain multiple "Wrong type 
argument" error messages, one for each diff. I have only tested this on 
a Windows box, so I don't know if this is a Windows-specific problem or not.

This is #17257 which is now fixed both in the emacs-24 branch and on
trunk.
