Merge branch 'jk/credential-clear-config'

The credential.helper configuration variable is cumulative and
there is no good way to override it from the command line.  As
a special case, giving an empty string as its value now serves
as the signal to clear the values specified in various files.

* jk/credential-clear-config:
credential: let empty credential specs reset helper list
