As \s is shorthand for the POSIX character class [:space:], I'd say the latter should be more portable: anything accepting the shorthand should also accept the full character class. If not, you probably only care about horizontal tab and space, for which you could just use a simple regular expression. Just a literal space and tab character between square brackets is probably going to be most portable, though not most readable. -Geert-- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
