I think the variant with threadStr[] and sizeof - 1 is more
maintainable, especially since not everyone uses Emacs.  Moreover, a
literal constant makes code a bit harder to read, since I need to
count characters after you, to be sure I understand exactly what your
code does.

Granted, it's a minor nit, but then so are our indentation and
whitespace rules.

(Btw, in stock Emacs "ESC =" counts _lines_ in region, not characters.
You probably have some customization that does this.)
