23.06.0

Changes since 23.05.0:

• README: add brew instructions (#302)
• Fix grc / forgit revert_commit (#305)
  This was accidentally broken since 450615d due to a wrong git call.
• Use correct IFS store/restore mechanism (#306)
  The previous implementation had the problem that if IFS was not set
  before, it was set to an empty string after restoring, which is not the
  same as being unset. This broke grc / git forgit revert_commit, since
  "git revert" was being interpreted as the command name instead of
  command and argument.
  The correct way is to check whether IFS is unset and, if so, unset it
  again afterwards.

• Allow configuration of checkout_branch branch cmd (#307)
• Restore support for appending FORGIT_INSTALL_DIR to path (#308)
  It seems somewhere along the line FORGIT_INSTALL_DIR stopped getting exported. According to the README you can append it to your path to get access to git forgit ... commands however this seems to no longer work - this is an attempt to restore this functionality.
• Allow passing parameters to forgit::reset::head (#309)
• Allow passing parameters to branch_delete and stash_show (#312)
