* Only way I can explain why the "3rd output is different from the 1st and
2nd":

You unwittingly placed a <Tab> character after the "::" on the 3rd row--and
you look at it and you believe its a <Space> character.

* Suggest you open it up in VI and do ":set list"--is there a "^I"
character there?

** Better yet, open the file up and use whitespace-mode in Emacs.

** Also suggest you use the POSIX compliant form for regular expressions
whenever possible--i.e. use [:blank:] when you mean " " and "[:space:]"
when you mean whitespace--that way its harder to fool yourself, and others
that read your code.
