Sitaram Chamarty d8df4a9344 git-config bugfix + backward compat breakage in usage of 'config'
(1) the backward compat breakage: you can't create empty-valued config
    keys anymore.  That is, you can't do the eqvt of the following shell
    command using gitolite

        git config foo.bar ""

(2) fixed a bug where this:

        repo foo
            config foo.bar =

    when queried using

        gitolite git-config -r foo .

    would return even the empty valued ones, which -- remember! -- are
    not supposed to exist anymore.

    Fixing this bug allows situations like this to not show the admin
    repo in gitweb:

        repo [a-z].*
            config gitweb.owner = P-h B

        repo gitolite-admin
            config gitweb.owner =

----

background...

Somewhere in g3 (well actually in 057506b), we lost the ability to
distinguish
    config foo.bar  =   ""
from
    config foo.bar =

I decided that conflating them is more intuitive for most people,
because a survey [1] revealed that no one seemed to want the equivalent
of the following shell command:
