From: Johannes Sixt <johannes.sixt@xxxxxxxxxx>
It seems that MSYS's wish does some quoting for Bourne shells, in
particular, escape the first '{' of the "^{tree}" suffix, but then it uses
cmd.exe to run the "git rev-parse" command. However, cmd.exe does not remove
the backslash, so that the resulting ref expression ends up in git's guts
as unrecognizable garbage.
Fortunately, recent versions of git can refer to the root tree object using
the notation "$commit:", which avoids the problematic case.
