Instead of an empty string as a configuration variable, using
something like no.such.variable that does not exist would also be
a workaround. I.e.,
RESET=$(git config get --type=color --default=reset no.such.variable)
What is bad about this is that there is no generic variable that is
guaranteed to be unset.
