A hacky way would be to use something like:

$ ack -g '\.h$' | xargs -d '\n' svn diff

Here it does this:

<<<<<<<<<
shlomif[fcs]:$trunk/fc-solve/source$ ack -g '\.h$' | xargs -d '\n' svn diff
Index: scans.h
===================================================================
--- scans.h (revision 3977)
+++ scans.h (working copy)
@@ -72,3 +72,4 @@
 #endif
 
 #endif /* FC_SOLVE__SCANS_H */
+hello
svn: 'prefix.h' is not under version control
shlomif[fcs]:$trunk/fc-solve/source$
>>>>>>>>

For information about ack, see:

As you can see, it warns because it finds non-versioned files. This can be
dealt with using:

$ ack -g '\.h$' | (while read T; do (svn info "$T" > /dev/null 2>&1) && echo
"$T" ; done) | xargs -d '\n' svn diff

Alternatively, you can use the Subversion APIs (or one of their higher
language bindings) to write a custom diff command.
