Unfortunately it doesn't seem to be there mechanism to query about
state of gitattributes at given commit.

There is a slight problem from the UI point of view of git-check-attr,
namely that there are _three_ pieces of information: a place to read
.gitattributes from (working tree, index, commit), list of attributes
to check (or --all) and list of files (list of paths).  You can use
"--" to separate _two_ pieces of information.

Nb. the ability to read gitattributes from given commit would be
useful also for gitweb (the `encoding` gitattribute, etc.).
