Oh, good catch!

I agree it would have helped in this case, but I’m not sure how to add

I think we need to keep the leading “.*” to match things like
‘x86_64-linux-gnu-gcc’. The rest looks good though. WDYT?
“guix refresh -l -e '(@@ (gnu packages gcc) gfortran)'” reports 854
dependent, which means we should apply it to ‘staging’.
