    I applied the code change to the kernel.  
    You're still breaking the man page.
    All the font lines are correct as they are.
    
    	uart.orig:22,30 - /n/sources/patch/uart-update-again/uart:22,32
    	  is accessed through
    	  .BI eia n
    	  (the data file),
    	- .BI eia n ctl
    	+ .BI eia n
    	+ .I ctl
    	  (the control file), and
    	- .BI eia n status
    	+ .BI eia n
    	+ .I status
    	  (the read-only status file).
    	  Reads of the data file will block until at least one byte is available.
    	  The
    
    The control file is really
    
    	.BI eia n ctl
    
    which formats the same as \fBeia\fIn\fBctl.
    What you have will format like (ignoring the fonts) "eian ctl",
    with an extra space.
    
    	  It accepts the following commands:
    	  .TP
    	- .BI b n
    	+ .B b n
    	  Set the baud rate to
    	  .IR n .
    
    This is okay the way it was too.  The "n" is a parameter, not
    a literal n, so it should be in I font, not B font.  If you 
    were trying to put in a space, you would use 
    
    	.B b\fI n
    
    (what follows .TP has to be one input line), but again here
    the space is incorrect.  The control message is just "b1", 
    not "b 1" (that's two different messages!).
