Add some conservative checks on function names: - Disallow expansions or quoting characters; these can only be called via strange control characters - Disallow '/'; these functions cannot be called anyway, as exec.c assumes they are pathnames - Make the CTL* bytes work properly in function names. These are syntax errors. POSIX does not require us to support more than names (letters, digits and underscores, not starting with a digit), but I do not want to restrict it that much at this time. Exp-run done by: pav (with some other sh(1) changes)
