merge: don't report progress for dr/rd actions...
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.

Test for issue2043: ensure that 'merge -P' shows ancestors of 6 that
are not ancestors of 7, regardless of where their common ancestors are.
Merge preview not affected by common ancestor:
$ hg up -q 7
$ hg merge -q -P 6
