annotate mercurial/upgrade.py @ 31899:cccd8e1538b0

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
upgrade: filter optimizations outside of 'determineactions' This sounds like higher level logic to process arguments. Moving it out of 'determineactions' will allow passing only deficiencies to the function. Then, in a future changeset, we will remove dispatch on "improvement type" within the function. See next changeset for details.
