Comment (by philderbeast):

 I use posh git and git from msys. I see that
 {{{%USERPROFILE%\.gitconfig}}} and {{{$HOME/.gitconfig}}} are the same
 file location. In any case, when I was unable to repeat the recursive
 clone, I tried every git client I have installed and all failed.
 Previously, one client, I can't remember which, had succeeded.

 I did have to run CHKDSK to repair the drive on which I was compiling and
 testing ghc. However, this is {{{E:}}}, not the {{{C:}}} system drive with
 git's global config. I don't see how this could explain losing the rewrite
 rule.
