ediff selective browsing

[Florian Kaufmann]

Hello

As I understand it, selective browsing works on a difference region
basis. I rather would like it to have on a per word basis. For example,
I have two pieces of code, which are very similar. The most often
difference is that a function foo has been renamed to bar. This type of
difference I want to step over. If I give ediff the regexs \<foo\> and
\<bar\> after pressing #h, it also steps over regions like this
buffer A: foo(1)
buffer B: bar(2)
This makes sense according to the documentation: both regions contain
my regex. However this is not what I want, because these two differ not
only in renaming foo to bar, but also in the argument of the function
call. What do I have to do that ediff only steps over difference
regions where the only difference is that occurrences of \<foo\> have
been replaced by \<bar\>?

Thank you

Flo
