Additionally, backticks are kinda-sorta deprecated. This means that
all the people who write the standards have said "Yeah, backticks suck
and the next standard will deprecate them" but standards bodies are
slow as hell, so they haven't made a new standard that deprecates them
yet

I think we need at least vim and emacs, though we can trim the vim line:
# vim: set noet ts=8 sw=8 tw=132

Aside: setting autoindent in a modeline is missing the point of
modelines. They're intended to describe the FORMAT of the file, not
how you should edit it.

This is bash specific, is it not? In projects such as initscripts we'd
want to steer away from this as, in theory, we could swtich to dash
some day.
