+   convention to catch mistyped paths is to make sure all the non-rev
+   parameters in the later part of the command line are names of the
+   files in the working tree, but that means "git grep $str -- \*.c"

+ * "git merge FETCH_HEAD" learned that the previous "git fetch" could

+   test by mistaken use of wrong kind of quotes.

+   for almost eternity, but the original use case the latter tried to
+   support was semi-bogus (i.e. install git to /opt/foo/git and run it
+   without having /opt/foo on $PATH), and more importantly it has
+   become less and less relevant as Git grew more mainstream (i.e. the
+   users would _want_ to have it on their $PATH).  Stop prepending the
+   path in which "git" is installed to users' $PATH, as that would
+   interfere the command search order people depend on (e.g. they may
+   not like versions of programs that are unrelated to Git in /usr/bin
+   and want to override them by having different ones in /usr/local/bin
+   and have the latter directory earlier in their $PATH).

+ * After "git add -N", the path appeared in output of "git diff HEAD"
+   and "git diff --cached HEAD", leading "git status" to classify it
+   as "Changes to be committed".  Such a path, however, is not yet to
+   be scheduled to be committed.  "git diff" showed the change to the
+   path as modification, not as a "new file", in the header of its
+   output.
+
+   Treat such paths as "yet to be added to the index but Git already
+   know about them"; "git diff HEAD" and "git diff --cached HEAD"
+   should not talk about them, and "git diff" should show them as new
+   files yet to be added to the index.
