CG 8.2.2 - Regular maintenance, verifying issues

[Federico Bruni]

Hi

I think that this page should be updated (there are links to google 
code tracker):
http://lilypond.org/doc/v2.19/Documentation/contributor/bug-squad-checklists

The most important part is the way an issue is verified.
Let's take this issue:
https://sourceforge.net/p/testlilyissues/issues/4639/

The committish is:
0f3099177a2a23347b0a8c0895adbebc87d416be

The doc recommends two ways to verify it:
http://git.savannah.gnu.org/gitweb/?p=lilypond.git
http://philholmes.net/lilypond/git

but, for some reason, both fail in searching that committish.
Same for gitk on my local copy.

But 'git show' works fine:
git show 0f3099177a2a23347b0a8c0895adbebc87d416be

Do you know why?

AFAIK, git log does not show if a commit was entered before a certain 
tag.
There's any better way to check it?
I found this command, but you must scroll and find the committish:

git log --decorate --all --oneline --graph

Ok, I found what I think it's the best command:

git tag --contains <committish>

$ git tag --contains 0f3099177a2a23347b0a8c0895adbebc87d416be
release/2.19.31-1

What do you think?
