    tmac/mdoc/doc-common-u: Fix style problems.
    
    Correct misleading indentation.
    
    Also fix spelling of register name.  Despite appearances, this wasn't
    actually a typo but a deliberate mispelling; I learned in the course of
    implementing 0438b1b905ebe9ac5fc678af06db911d25c3a030 (14 September)
    that removing a non-existent register was not an error (or even a
    warning) condition.  I looked briefly into adding code to warn about it,
    found it difficult--the string that's used for lookup in the register
    dictionary seems to not actually be in the scope of `remove_reg()`,
    which implements the '.rr' request--at any rate it's not a "symbol"
    because undefined symbols are reasonably enough not in the troff symbol
    table, and I don't know the class hierarchy well enough to guess where
    else it might be.  I then forgot to revert the change I was using to try
    to provoke the diagnostic, and didn't notice because...there's no
    diagnostic.  (One could still be emitted from `remove_reg()`, but it
    wouldn't be able to include the name of the unrecognized identifier, and
    I consider that too user-hostile to bother with.)  Anyway, this is an
    object lesson in using "XXX" comments.
