It's an old trick. If you have a range, e.g. a-z, then "-" is 
interpreted as the range separator.  So if you wanted to include a 
literal "-" in a []  regex set, you had to put it first or last, since 
then it could not be part of a range. The ability to escape - using \ is 
much newer, and apparently not supported on AIX.
