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 "git rev-parse". However, cmd.exe does not remove the
backslash, so that the resulting rev expression ends up in git's guts
as unrecognizable garbage: rev-parse fails, and git-gui hickups in a way
that it must be restarted.
Fortunately, recent versions of git can refer to the root tree object using
the notation "$commit:", which avoids the problematic case.

This is a resend with a slightly improved commit message.
The first version didn't get through for some reason anyway, it seems.
