directaccess: fix case of shortened hash containing only digits
For directaccess, there are four cases for what looks like short hashes made
of digits only:
1 | the hash is a revision number and not a short hash for another revision:
we don't change the visibility
2 | the hash is a revision number and a short hash for another revision:
we don't change the visibility
3 | the hash is not a revision number and not a short hash for another revision:
we don't change the visibility
4 | the hash is not a revision number but is a short hash for another revision:
we make it visible
Before the patch we were not lifting visibility in case number 4. This patch
fixes the issue.
