lib.cli.escapeShellArg{,s}: Only escape when necessary ( #333744 )
...
These utilities will now leave the string undisturbed if it doesn't need to be quoted (because it doesn't have any special characters). This can help generate nicer-looking command lines.
This also transitively improves the output of `lib.toGNUCommandLine` which uses `escapeShellArg` internally

lib.strings: add trim and trimWith
...
`strings.trim` returns a copy of the string with all leading and trailing
whitespace removed.
`strings.trimWith` does the same thing, but calling code can decide
whether to trim the start and/or end of the string.

lib/customization: propagate function arguments in callPackagesWith
...
makeOverridable is very careful to ensure the arguments to the
overridden function are the same as the input function. As a result,
the arguments of hello.override are exactly the same as the original
arguments of the hello function that produced the derivation.
However, callPackagesWith calls makeOverridable with a lambda that
does not propagate the arguments. The override function for a package
instantiated with callPackagesWith will not have the original
arguments.
For example:
nix-repl> lib.functionArgs hello.override
{ callPackage = false; fetchurl = false; hello = false; lib = false; nixos = false; stdenv = false; testers = false; }
nix-repl> lib.functionArgs openssl.override
{ }
By copying the arguments onto the inner lambda before passing it to
makeOverridable, we can make callPackage and callPackages behave the
same.
nix-repl> lib.functionArgs openssl.override
{ buildPackages = false; coreutils = false; cryptodev = false; enableSSL2 = true; enableSSL3 = true; fetchurl = false; lib = false; perl = false; removeReferencesTo = false; static = true; stdenv = false; withCryptodev = true; withPerl = true; }

lib.sortOn: init
...
A more efficient sort in some cases, and often convenient.
This exposes `lib.lists.sortOn` immediately on `lib`, because it is
a sibling of `sort`, which is already present there.
Omitting it would lead to more confusion, and worse outcomes.
There's no confusion about the types `sort` or `sortOn` operate on.
Haskell agrees about the type for `sortOn`, and it is in its `base`.
