git --literal-pathspecs add -u says "fatal: pathspec ':/' did not match any files"

~/tmp/tmprepo$ git init Initialized empty Git repository in /home/npostavs/tmp/tmprepo/.git/ ~/tmp/tmprepo$ git --literal-pathspecs add -u fatal: pathspec ':/' did not match any files ~/tmp/tmprepo$ git --version git version 2.6.1

It was reported[1] that 2.0.2 and several following versions also fail with the same error; I found that version 1.9.5 succeeds.

Adding a "." argument:

   git --literal-pathspecs add -u .

succeeds in all versions.
