Functions

func IsAlphaNumericIsh

func IsAlphaNumericIsh(s string) bool

IsAlphaNumericIsh returns whether s contains only ASCII alpha-numerics and a limited set of punctuation such as commas and slahes, but not containing e.g. spaces, semi-colons, colons or backslashes.

The intent is that if s is alpha-numeric-ish, then it should not need escaping when passed to other programs as command line arguments.
