Update to 0.18.2:

>From the release announce mails:

   I've released cogito-0.18.2, bringing a couple of bugfixes and a trivial new
 feature to cogito-0.18.1. Still nothing too groundshattering.

 * cg-log does not follow history across renames anymore; it never really
   actually worked and was instead causing problems and random error
   messages. There needs to be git-core support for this funcionality,
   hacking it with a perl filter is bad design, so I'm not going to fix
   the filter (but I'd take patches if someone else did ;).

 * Fix cg-init not letting you edit the initial commit message by default
 * Fix cg-clone -l which would not setup alternates properly in some cases
 * Fix cg-merge not picking the right base when following volatile branches
 * Fix cg-log -d sometimes showing "% @" in diff output
 * Some other minor fixes

 * New cg-object-id -b to print the current branch name

 * Documentation improvements (better documented ignoring mechanism,
   ~/.gitconfig mentioned, GIT_COMMITTER_* bogus information fixed, ...)
 * Some testsuite fixes

    I've released cogito-0.18.1, bringing few minor new features and
  random bugfixes to the cogito-0.18 version. Nothing groundshattering.

  * cg-switch -c as a shortcut for cg-switch -r HEAD - use it to create a new
    branch with less typing
  * cg-patch -e to edit log message before autocommitting (useful esp. as
    cg-patch -m -e)
  * Support for cg-version --lib-dir, --share-dir
  * cg-admin-rewritehist now defines a map() function for filters' use,
    translating from old to new commit ids
  * cg-commit -e now runs editor on /dev/tty even if input is not a tty
  * Trivial documentation improvements
  * Random details fixed
