revert: use an exact matcher in interactive diff selection (issue5789) When going through _performrevert() in the interactive case, we build a matcher with files to revert and pass it patch.diff() for later selection of diff hunks to revert. The files set used to build the matcher comes from dirstate and accounts for patterns explicitly passed to revert ('hg revert -i <file>') and, in case of nonexistent pattern, this set is empty (which is expected). Unfortunately, the matcher built from scmutil.match(ctx, []) is wrong as it leads patch.diff() to rebuild a 'changes' tuple with dirstate information, ignoring user-specified pattern. This leads to the situation described in issue5789, where one gets prompted about reverting files unrelated to specified patterns because they made a typo or so. We fix this by building an exact matcher with the correct set of file paths (built earlier). Thanks to Yuya Nishihara for suggesting the correct fix.
