# Completion configuration
#
# It's worth noting what's going on here since it's not clear from the
# documentation.
#
# There are three cases to cover for the behavior I want:
#   - Only one match → complete
#   - Multiple matches → show the list
#   - Multiple matches with common prefix → complete prefix and show the list
#
# By default, `menu-complete()` will select the first completion, this covers
# the first case. `show-all-if-ambiguous` covers the second case by showing the
# list when there are multiple choices. `menu-complete-display-prefix` covers
# the third case by completing the common prefix.
