But then you don't see additional information about section names that
may help to select the necessary manual.  So I tend to agree with your
implementation in man-completion.el that provides completions in
3 formats: without a section name, with the section name appended
in parens, and prepended at the beginning:

    "chmod"
    "chmod (1)"
    "chmod (2)"
    "1 chmod"
    "2 chmod"
