Code review comment for lp:~zorba-coders/zorba/bug-1123161

I do have two minor points, but they're just about comments so I'll go ahead and leave my Approve vote too.

First, one minor typo: "ahe" instead of "the" in regex.cpp.

Second, question about comment:

     //
     // The '=' is neither the first or last character within a
     // character range (i.e., a literal '-') so therefore it's
     // indicating a character range.
     //

Is there some context about '=' that I'm missing, or is that just a typo and it should be '-'?
