Logview 0.15.1

This release works around an incompatibility with Emacs 29 (not yet released) that would cause unpredictable bugs up to a full freeze of Emacs in its fontification code. The workaround is not perfect and maybe will never be, but that largely depends on what Emacs developers do. At the very least, all unpredictable errors should be replaced with a predictable one that won’t cause Emacs to hang.
