Not really. It fixed "git add -u path", not plain "git add -u". A quick
test checking out and compiling v1.5.2.5~1^ shows that "git add -u ."
from a subdirectory was adding everything from the root.

My interpretation is that v1.5.2.5~1 fixed an actual bug, without
thinking about what would happen when "git add -u" was called without
path, so the behavior is "what happens to be the most natural to
implement". Indeed, the behavior was actually documented only later, in
v1.5.4.3~3 (Feb 21 00:29:39 2008, Clarified the meaning of git-add -u in
the documentation), the previous doc said only "If no paths are
specified, all tracked files are updated.".
