[p4] Sync updates the revision number of open files

[Robert McKenna]

Hi
I having a problem in which users who have a file open for edit at say
revison 10, sync to a newer without submitting their changes. This does
not overwrite the users changes but does update the revision number in
the changelist and client view while scheduling the file for resolve. A
warning is issued in the command output, which is easy miss when syncing
large numbers of files, particularly as we use automated update tools
and also have integrations that require extensive manual merging. This
leaves the user confused to say the least.
 
Does anyone know how to prevent this? It is technically user error but
in our situation is almost certain to happen on a regular basis.
