[PATCH v2 44/46] pathspec: make --literal-pathspecs disable pathspec magic

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

--literal-pathspecs and its equivalent environment variable are
probably used for scripting. In that setting, pathspec magic may be
unwanted. Disabling globbing in individual pathspec can be done via
:(literal) magic.
