How to delete old universal abbreviations

[nap2001]

Since release 3.6.0's enhancements to abbreviations, I need to rethink/redesign/cleanup my abbreviations. How do I get rid of my pre-3.6.0 universal abbreviations? I've tried "abbr -e" but that only deletes in the current shell and new shells still have the deleted old abbreviation. I have 105 universal abbreviations and think I should just start over given changes in 3.6.0.

echo set -e (set -Un | string match -re '^_fish_abbr_')

remove the echo if you're happy.

I opened #9468 to track making abbr -e work.
