This breaks compilation with go 1.17, meaning it will force projects to upgrade to go 1.18.
With the multitude of projects using cobra, there very well may be some using go 1.17 (or even 1.15 or 1.16).

Although it may be time to let go of these Go versions I want this to be a conscious decision. And if we go that route we’ll need to update CI and cobra go.mod.

Also, I have to look at why CI didn’t run completely with this change which would have detected this early.

@mikelolasagasti @thaJeztah can to clarify the value of this change?

Looking from my phone, but my first guess would be this PR; I think that would be ok to revert to keep compatibility as it's not critical; WDYT @cpuguy83 ?

• md2man.go: rename ioutil to io cpuguy83/go-md2man#125

[cpuguy83]

That's fine.

☝️ I opened a PR to fix compatibility; once that (and related PRs) are reviewed and merged, we can probably tag a v2.0.6 and update here.

• Preserve compatibility with go <= 1.17 cpuguy83/go-md2man#130

@marckhouzam v2.0.6 was tagged; I opened a PR to update; #2206

Thanks for dealing with this so quickly @thaJeztah @cpuguy83
