You lean new things every day ;-).

The whole point of show-cdup is that people (especially those in
java land) bury themselves in a hierarchy so deep that it is not
feasible to tell "Go count the hierarchy and prefix that many ../
yourself" to them.

The answer to "we cannot count ../" issue is ":(top)" aka ":/" magic
pathspec modifier.

"git blame" takes a single pathname, not "a set of patterns to match
against to select concrete paths", which is what a pathspec is.
