Or better yet, if given installation of gitweb supports it, on the
'patch' link just on the right of 'raw' view.  Such patch can be
applied better by git-am (but both should work for GNU patch or
git-apply).

Yes, by default for merges the 'commitdiff' view (and the 'raw'
version, i.e. 'commitdiff_plain' view) shows **combined** diff of
changes brought by merge (see git-diff manpage for details on this
format).

For merge commit you have to choose which of parents you want to have
diff from.  Go to 'commit' view, there in the header would be two or
more parents.  Click on the 'diff' link beside chosen parent, check if
it is the diff you want to get, and then click on 'patch' (or 'raw')
link.
