addremove/findrenames: find renames according to the match object (issue1527) Instead of only finding similarities in the added/removed files found by the addremove step, follow the match object: hg addremove -s80 foo -> add and removes files in foo + find similarities between files in foo hg addremove -s80 -> add and removes files in the whole repo + find similarities between files in the whole repo hg import --similarity will still work correctly (only find similarities between files found in the patch).
