When I try to set the following keybind:
bind " " expand-abbr or self-insert
(with the intention to disable adding a space directly after expanding an abbreviation), fish crashes when there is nothing to expand. So expanding works fine, but the "or" case causes the following crash:
error: /build/fish-lfQFzD/fish-3.5.0/src/reader.cpp:4069: failed assertion: should have been handled by inputter_t::readch
