That probably makes sense, since there's only one place where it is
used, and it is for EVIOCGBIT decoding.

Unfortunately, no.  The overall gist is to process all "named
constant"-like data through print*{xlat,flags,xval} and the like in
order to be able to configure its representation freely (so far, it's
-X raw/verbose, but I'm also thinking about adding custom output
formatting options, like oct/dev/hex, or so).
