It seems SVN's "patch" functionality is not exactly what I want. What I really want is to create a diff of files between revisions. So, I'd choose rev1 and rev 2 and end up with a folder containing all files that were changed or added between those revisions.
Can this be done with Tortoise SVN or plain-old svn?
This can be achieved in tortoise SVN itself. Right click on the branch(folder) from where you want to create the patch >> Show Log
>> Select All the revisions for which you need to create the patch >> Right Click and select Compare revisions
>> This will show the changed files >> Select all the files >> Right click and select Export Revision To
>> Give any path in your machine >> The files will get exported in the respective folder structure.
Alternately you can achieve this via scripting. Refer the following link for that:

From the command line you could do this as follows.
All files in a folder
Create a patch in your Home folder that contains all the changes between revision 123 and 124 from all the changed files in the folder "my_project":
svn diff -r123:124 path/to/my_project > ~/my_project_changes_123_124.patch
One particular file
Create a patch in your Home folder that contains all the changes between revision 123 and 124 from only one file, name "my_project.php":
svn diff -r123:124 path/to/my_project/my_project.php > ~/my_project_changes_123_124.patch
Um...how about svn diff
? Just pass it the desired revisions.

In TortoiseSVN, if you highlight the revisions you want in the "show log" dialog, there is even a context menu item to show the changes as diff which you can then save off somewhere.
