Suppressing the No Changes confirmer during update

Hi All,

   I guess because of the multiple ancestors in the Spur bootstrap packages whenever I update a Spur image I see lots of annoying "No Changes" confirmers popping up that have to be clicked on to continue.  They come from

resolveConflicts

(records allSatisfy: [:ea | ea isAncestorMerge]) ifTrue: [MCNoChangesException signal. ^ false].

^ ((MCMergeResolutionRequest new merger: merger)

signal: 'Merging ', records first version info name) = true

I see a handler for MCMergeResolutionRequest in 

upgrade

^self depsSatisfying: [:dep | dep isFulfilledByAncestors not]

versionDo: [:ver | 

(self class upgradeIsMerge and: [ver shouldMerge])

ifFalse: [ver load]

ifTrue: [[ver merge]

on: MCMergeResolutionRequest do: [:request |

request merger conflicts isEmpty

ifTrue: [request resume: true]

ifFalse: [request pass]]]]

displayingProgress: 'upgrading packages'

am I right to think that's also the place to put a handler for the MCNoChangesException notification?
