Yup, there is no need for that inner dq pair in this particular case.
I was more worried about scripted Porcelains, like
: "${GIT_OBJECT_DIRECTORY="$(git rev-parse --git-path objects)"}"
which I think can safely lose the outer dq pair. In t/ directory,
there is this one in test-lib-functions.sh which I do not offhand
know how these problematic shells would handle.
echo "#!${2-"$SHELL_PATH"}" &&
Other than the presence of these two that are not covered by this
patch, the patch itself looks good. Thanks.
