It should be straightforward to add

  (setenv "GROFF_NO_SGR" "1")

somewhere in man.el.  I don't know the right location...

Yes and no :-) I decided to make SGR the default output format of
groff's TTY output device starting with groff version 1.18 about six
months ago.  Not all tools understand SGR yet, so it will take some
time until everything has been updated.  Setting this environment
variable will always work regardless of the used version of man or
groff, so I think this is the easiest workaround within Emacs.
