String#chomp!

(nil) -> nil

(?::string? separator) -> self?

chomp!(line_sep = $/) → self or nil

static VALUE
rb_str_chomp_bang(int argc, VALUE *argv, VALUE str)
{
    VALUE rs;
    str_modifiable(str);
    if (RSTRING_LEN(str) == 0 && argc < 2) return Qnil;
    rs = chomp_rs(argc, argv);
    if (NIL_P(rs)) return Qnil;
    return rb_str_chomp_string(str, rs);
}

Like String#chomp, except that:

Removes trailing characters from self (not from a copy of self).
Returns self if any characters are removed, nil otherwise.
