[v3,2/6] usage.c API users: use die_message() where appropriate

Commit Message

Ævar Arnfjörð Bjarmason Oct. 22, 2021, 6:19 p.m. UTC

Change code that either called error() and proceeded to exit with 128,
or emitted its own "fatal: " messages to use the die_message()
function added in a preceding commit.
