Hello,

The man page for git commit-tree shows weird text under the DIAGNOSTICS section:

    You don't exist. Go away!

    The passwd(5) gecos field couldn't be read
    Your parents must have hated you!
    The passwd(5) gecos field is longer than a giant static buffer.
    Your sysadmin must hate you!
    The passwd(5) name field is longer than a giant static buffer.

I noticed that the same happens for Documentation/git-var.txt

Is this normal or?
