Undo groups on cursor movement ?

[Tommaso Cucinotta]

Hi,

if I start LyX with -dbg undo, why do I get the creation of 3 undo 
groups for each single (read-only) cursor movement ?

For example, just moving right over a letter, gives me:

Undo.cpp(498): +++++++Creating new group 11
Undo.cpp(511): -------End of group 11
Undo.cpp(498): +++++++Creating new group 12
Undo.cpp(511): -------End of group 12
Undo.cpp(498): +++++++Creating new group 13
Undo.cpp(511): -------End of group 13

Merely moving the cursor doesn't seem to need to involve any undo logic!
