Skip gitlink modes as we can't get a content difference
A gitlink mode doesn't have a blob file contents, which means we
can't get its hunk edit list to store in the cache, and we most
certainly can't read its target as though it were a blob with lines.
Currently we are reading a 1 line delta on these files coming back
from git-diff-tree because git-diff-tree is doing a pretty-printing
that looks like this:
diff --git a/modules/parser b/modules/parser
-Subproject 88dde83e6f7c09e44f5a03420fcff44145d89b2
+Subproject dabca1dfbedb13a105003a8adcbb777fe87883b
This is bogus, and not what we want. So jump out early and cache
an empty edit list, since there isnt't really a text line being
replaced in this path name.
