I agree.

I do want svn:eol-style set on those in case somebody checks out a 
working copy on Windows, modifies those files and checks them back in. 
That would introduce CRLFs into them and gratuitous diffs.

I'm of the mind that mostly everything should have svn:eol-style set 
except for those files that shouldn't have it, such as the patch files.

Which are those?

Right, it's not appropriate for the patch files.  For non-patch files, 
it is appropriate and I would rather leave them on.  So that's why I 
suggested my glob, to remove it from patches and leave it on everything 
else.

I disagree.  Take it off of the */*/patch* and the 200 other patches, 
which I guess are poorly named then since they don't start with the word 
patch, and leave everything else alone.

Granted your pass is less work, but it results in a less correct repository.

I did a pass through Portfiles a while ago to set it on every Portfile.
