ocamlPackages.astring: 0.8.3 -> 0.8.5
Since astring is a common dependency and the maintainance effort is
minimal (package dependencies and build system didn't change) we keep
the old 0.8.3 version around for OCaml < 4.05, since 0.8.4 requires a
minimum of OCaml 4.05.

longDescription = ''
Astring exposes an alternative String module for OCaml. This module tries
to balance minimality and expressiveness for basic, index-free, string
processing and provides types and functions for substrings, string sets
and string maps.
Remaining compatible with the OCaml String module is a non-goal.
The String module exposed by Astring has exception safe functions, removes
deprecated and rarely used functions, alters some signatures and names,
adds a few missing functions and fully exploits OCaml's newfound string
immutability.
