Duplicate test numbers in pu.

Hi Junio,

I noticed that the pu branch has two tests with number t0007, viz:

    $ cd t
    $ make test-lint-duplicates
    duplicate test numbers: t0007
    make: *** [test-lint-duplicates] Error 1
    $ 

In particular, t/t0007-git-var.sh is added by branch 'jk/send-email-\ sender-prompt', while t/t0007-ignores.sh is added by branch 'as/check-ignore'.

Also:

    $ make test-lint-executable
    non-executable tests: t5801-remote-helpers.sh
    make: *** [test-lint-executable] Error 1
    $

(added in branch 'fc/fast-export-fixes').

HTH
