The one that comes with Emacs 25.1. For example (with a custom theme to
make strings stand out):

echo this should be a string, right?
foo %alpha
foo %alpha_beta
foo "%alpha"set alpha=gammaset alpha_beta=gamma
foo foo.in

I see this in Emacs 25.1, for example:

echo "<<test"
test

I reported this over a year ago, for Emacs 25.0.93, see bug#23526.


I also see a reference to "bell_206.ps" but I can't find this file.

It's from http://people.sc.fsu.edu/~jburkardt/data/ps/ps.html -- I'll see
if I can add it (or update the doc).
