Profpatsch 4a7f99d55d treewide: with stdenv.lib; in meta -> with lib;
Part of: https://github.com/NixOS/nixpkgs/issues/108938

meta = with stdenv.lib;

is a widely used pattern. We want to slowly remove
the `stdenv.lib` indirection and encourage people
to use `lib` directly. Thus let’s start with the meta
field.

This used a rewriting script to mostly automatically
replace all occurances of this pattern, and add the
`lib` argument to the package header if it doesn’t
exist yet.

The script in its current form is available at
https://cs.tvl.fyi/depot@2f807d7f141068d2d60676a89213eaa5353ca6e0/-/blob/users/Profpatsch/nixpkgs-rewriter/default.nix

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.
