Subject: if statement modifier, with else, warning

The following statement works fine, even though it generates a warning.
With regard to "if" and "unless" being used as statement modifiers, a
manual states: "Obviously, this syntax does not allow any kind of else
clause."

  compare_files unless @filename_1 == nil or @filename_2 == nil else
    @messagetextctrl.append_text("  ==> Please specify files to compare.
\n")

Error Msg: "...rb:112: warning: else without rescue is useless"

Obviously, the statement can be changed to the normal "if-else-end"
format, but that would not be as Ruby-ish as the above approach.

Is there a good reason why Ruby should not allow "else" to be used as in
the example above?
