[PATCH] git-submodule fixes for call to git config --get-regexp

["Chris Larson" <clarson@kergoth.com>]

Two minor git-submodule fixes:
* Escape !'s in the git config --get-regexp, so submodule paths can
contain them.
* Be more explicit about the value regex, otherwise things get confused if one
  submodule name is a prefix of another (since --get-regexp can return
  multiple values).
