[PATCH v2 0/2] MR2279: riched20: Don't set para unless committing cursor move in ME_MoveCursorWords. (#54564)
Introduce a temporary variable, `other_para`, so that we don't end up returning incorrect para (with stale run) inside the output cursor. Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=54564 -- v2: riched20: Don't set para unless committing cursor move in ME_MoveCursorWords. riched20/tests: Test for word movement across paragraph boundary. https://gitlab.winehq.org/wine/wine/-/merge_requests/2279
