What's with the overly-noisy quoting of dashes here?  To match a
string that happens to begin with a dash, either one of

	$ grep -e "-this string begins with and has-many-dashes-in-it" file
	$ grep "[-]this string begins with and has-many-dashes-in-it" file

would be sufficient and more idiomatic.

Or am I missing some other reason why the test is written this way?

No, it's just my lack of experience. Thanks for your fix! I have applied 
it in V3.
