[Bug 1804686] [NEW] "Formatting control flags" mentioned in man page are absent

[Moses Moore]

Public bug reported:

The man page for 'gofmt' describes three 'Formatting control flags':
-comments=true , -tabs-true, and -tabwidth=8.  If I attempt to use them,
I get i.e. "flag provided but not defined: -tabs"

Steps to reproduce:

gofmt <<<"package main"  # success
gofmt -invalidflag=true <<<"package main"  # failure, as expected
gofmt -comments=true <<<"package main"  # failure, unexpected
gofmt -tabs=true <<<"package main"  # failure, unexpected

the '-comments', '-tabs' and '-tabwidth' are removed from gofmt in
version 1.11.2, but I am using gofmt version 1.10 from Ubuntu.  If this
change was backported to golang-go 1.10~4 then the manpage should be
updated to match.
