Subject: [PATCH] show-changes: Fix excessive quoting

Single quotes inside a line like below are treated as a part of the
value:

: "${foo:='bar'}"

If foo is empty or unset then it will be set to "'bar'", instead of
just "bar". This resulted in the script complaining that git can't
operate on directory "'scripts'".
