commit 2259c7d698afaf49d4a8d490f980707e2d479a4d
Author: Christopher Wellons <well...@nullprogram.com>
Commit: Christopher Wellons <well...@nullprogram.com>
Properly distinguish word and symbol constituents.
Using backward-kill-word was behaving inconsistently with other modes.
Characters like _ should be symbol constituents, not word constituents.
Use superword-mode to override this, just as in other modes.
