The perl string literal 'hi\there' has 8 characters: h, i, \, t, h, e, r, e

The perl string literal "hi\there" has 7 characters: h, i, <Tab>, h, e, r, e

'hi\there' #has eight characters and represents"hi\there"

was confusing so I updated it to:

'hi\there' #has eight characters and represents"hi\\there" (one \ in the string)

More importantly, however:

'blah\\blah' #has ten characters and represents "blah\\blah"

was incorrect so I updated it to

'blah\\blah' #has nine characters and represents "blah\\blah" (one \ in the string)

Thanks for the note. Next time, please don't remove the "Re^X:" from the front of the title.
