    [man]: Fix extra space when `ME`, `UE` + -mandoc.
    
    [man]: Fix extraneous space when `ME` or `UE` given extraneous arguments
    and mandoc wrapper is used.
    
    * tmac/an-ext.tmac (UE, ME): Double backslashes in macro definitions
      when interpolating `.$` register (just like we tell everyone else to
      do).  This one was interesting to track down.  When using just `-man`,
      the problem never manifested; only with `-mandoc`.  The difference is
      that with the former, the `.$` register is initialized to zero; with
      the latter, because `TH` is aliased to another macro (then unaliased),
      `.$` has the argument count to the `TH` macro, not to the macros
      actually being called.  This caused the wrong branch of a conditional
      to be taken and put an extra space node on the output.  And all this
      to interpolate arguments we don't even claim to support. :|
