Dave,
Robert has purposed a very simple fix just like mine. I have an option
to turn on/off the filtering of these config lines except I use the
syntax /^set spantree port.*/ because it will catch both of those
possible output lines and leaves the valid stuff.
In regard to the changes of spanning-tree stuff on IOS it will not show
up in your config thus never showing up in the CVS diff. The
differencing normally for something to show up IOS based is due to info
changes in the storage areas (flash/bootflash/etc). I personally have
ignored those commands as they serve no purpose for me. I would suggest
doing the same unless you have a very particular reason to capture the
images tha are stored on your devices.
