I don't know why I thought this was undocumented.  Werner added this sentence
to the .ce section of the manual back in 2000
([http://git.savannah.gnu.org/cgit/groff.git/commit/?id=e9b0d52de commit
e9b0d52de]): "The basic length for centering text is the line length (as set
with the 'll' request) minus the indentation (as set with the 'in' request)."
Today this reads, "center the output ... with respect to the line length and
indentation without filling."
