The result text can be modified by hand as you like.
There is just one constraint: the editor will prevent you from
removing the target places of the various conflicts.
You can modify the text in and out of conflicts place. You
can also modify the bottom limit of conflicts as well. Full
undo/redo is provided so that hand-typed resolution will not be
lost, even if overwritten by a global 'Select All + Resolve' or
'Resolve' command. Undo/redo will as well restore limits of the
conflicts so that Merge does not get confused with conflict
limits modifications.
The result text will be saved to the location(s) you set as
"output location" (ie one or more from left/ancestor/right
items and/or another location, specified in the bottom
view).
