blame: Un-break isFile check in tree walk
Originally, blame's walk to find a scapegoat to blame for a file
walking backward from a commit used the test
treeWalk.getFileMode(0).getObjectType() != OBJ_BLOB
to throw out gitlink (submodule) entries. Later, 52500d3264d2 (blame:
Micro optimize blob lookup in tree, 2014-04-17) changed that test to
(treeWalk.getRawMode(0) & TYPE_FILE) != TYPE_FILE
These checks are not the same, though: the older test accepts files
and symlinks, while the newer one accepts files, symlinks, and gitlink
(submodule) entries. This is particularly broken in the submodule
case --- trying to parse the referred-to commit as a blob produces
caught an exception: GET /gerrit/+blame/master/plugins/reviewnotes HTTP/1.1
org.eclipse.jgit.errors.MissingObjectException: Missing blob 61702414c046dd6b811c9137b765f9db422f83db
Stick to just (possibly executable) files instead. Symlinks are not
line-oriented data so blame on a symlink is not likely to be useful.
A quick grep for '& TYPE_' doesn't find any other instances of this
bug.
