Bug#881040: chromium: No distinction between --incognito and --temp-profile in the manpage

[Nomen Nescio]

Package: chromium
Version: 58.0.3029.110-1
Severity: minor

Dear Maintainer,

Is there a difference between:

  $ chromium --temp-profile

and

  $ chromium --incognito

?  If so, it should be documented in the manpage.  If not, then the
--temp-profile option should be removed.
