Without considering compatibility issues, leading/trailing spaces should be validated or removed by user input validation/filter code in the first place. I think many users use "$" for the end of string data for regex, but it includes newline. To be precise, "\z" should be used for both PCRE and mbregex. http://perldoc.perl.org/perlre.html Trailing newline is invalid. Leading/trailing spaces may be considered as the same invalid data to be strict. This is what I thought for this. I don't have strong opinion. Regards, -- Yasuo Ohgaki yohgaki@ohgaki.net
