[fpc-pascal] A Regular Expression failing on the borders of words

Well, I need to study more. I can't understand what is wrong. The
match starts with a blank space: \s+. Some string follows: .*. And it
ends in the border of word: \b. So, (\s+.*\b)*, for me, should return:
+ABC +DEF. If "@" is not present, why the rest of the string was

My knowledge about Regular Expressions is small, so I really need to study more.
