+This simplifies the traversal of regions of results and eliminates the\r
+need for save-excursions (which tend to get in the way of maintaining\r
+point when we make changes to the buffer). It also fixes some strange\r
+corner cases in the old line-based code where results that bordered\r
+the region but were not included in it could be affected by region\r
+commands. Coincidentally, this also essentially enables multi-line\r
+search result formats; the only remaining non-multi-line-capable\r
+functions are notmuch-search-{next,previous}-thread, which are only\r
+used interactively.\r
