Peter Simons 3e09798bf4 pkgs/shells/bash/default.nix: revert my earlier revision 29244
Including the bash-completion package in bash itself sounded like a good idea
at the time, but it wasn't. After having actually integrated completion support
into NixOS, it has become obvious that this property isn't required at all.
Keeping bash-completion separate from bash works just fine. Anyone who wants
completion support can just install that package.

longDescription = ''
Bash is the shell, or command language interpreter, that will
appear in the GNU operating system. Bash is an sh-compatible
shell that incorporates useful features from the Korn shell
(ksh) and C shell (csh). It is intended to conform to the IEEE
POSIX P1003.2/ISO 9945.2 Shell and Tools standard. It offers
functional improvements over sh for both programming and
interactive use. In addition, most sh scripts can be run by
Bash without modification.
