merge: don't report progress for dr/rd actions
It is easier to reason about certain algorithms in terms of a
file->action mapping than the current action->list-of-files. Bid merge
is already written this way (but with a list of actions per file), and
largefiles' overridecalculateupdates() will also benefit. However,
that requires us to have at most one action per file. That requirement
is currently violated by 'dr' (divergent rename) and 'rd' (rename and
delete) actions, which can exist for the same file as some other
action.
These actions are only used for displaying warnings to the user; they
don't change anything in the working copy or the dirstate. In this
way, they are similar to the 'k' (keep) action. However, they are even
less action-like than 'k' is: 'k' at least describes what to do with
the file ("do nothing"), while 'dr' and 'rd' or only annotations for
files for which there may exist other, "real" actions.
As a first step towards separating these acitons out, stop including
them in the progress output, just like we already exclude the 'k'
action.
