Note that this will only match if the sentence is on a line by itself,

Are you sure about that? I thought they just meant that the string
begins with, and ends with, the enclosed characters. I didn't think
they actually refered to end-of-line indicators, the same markers are
used in wildcarding where there isn't a notion of "lines" (e.g. URIs).

Using a URI is not the same as having the bash shell interpret the
command line.
In bash (and regexes) in the format used above the ^ literally means
"line begins with" and the $ means "line ends with"

To have it match anywhere in the line you must remove those special
characters.

Try it yourself if you need proof.
