Comment (by rwbarton):

 This kind of diff with no context is hard to read and in danger of getting
 out of date with upstream. Can you attach a diff produced by `git diff`
 or, failing that, at least with `diff -u`? (I think the attached diff is
 backwards, too.)

 Also, a documentation patch would be helpful. It's somewhat less obvious
 how I'm supposed to use a local .ghci_history file than a local .ghci
 file, since a .ghci file is written by the user, but a .ghci_history is
 (usually) produced by .ghci. Am I supposed to just create an empty
 .ghci_history file in the directory where I want to use local history?
