Comment:

 For the record, the specification says the following:
 > `$XDG_CACHE_HOME` defines the base directory relative to which user
 specific non-essential data files should be stored. If `$XDG_CACHE_HOME`
 is either not set or empty, a default equal to `$HOME/.cache` should be
 used.

 Indeed `.ghci_history` is rather non-essential.

 However, what is the argument for singling out `.ghci_history`? GHC puts
 all kinds of things in `~/.ghc`, including the user package database.
