I guess you tried this in Fundamental mode or somesuch? Wow! This is really confusing! [:space:] is defined by POSIX, and the manual even refers to it: A character alternative can also specify named character classes (*note Char Classes::). This is a POSIX feature. [...] You must not change its behavior! Making it depend on the major mode is even worse. If the intent is to have a different meaning, a different name should be chosen, such as [:whitespace:] (though I'm not sure whether some names are reserved by POSIX). -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
