Subject: update-index -h: show usage even with corrupt index
X-Git-Tag: v1.7.4-rc0~65^2

update-index -h: show usage even with corrupt index

When trying to fix up a corrupt repository, one might prefer that
"update-index -h" print an accurate usage message and exit rather
than reading the repository and complaining about the corruption.

[jn: with rewritten log message and tests]
