# Fuzzy-known source: surfaces fixes already taught for a command that
# *starts the same way* as this one, since f()'s own p lookup only ever
# matches the exact, literal string.
#
# Matches only against the KEY (left of "="), not the whole line -- an
# earlier version used `grep -F "$first_word " p`, which also matched
# inside a fix's *value*. Proven wrong live: with p containing
# `gti --version=gti(){ command git "$@"; }`, querying "git push" (never
# taught) matched that line anyway, because "git " appears inside the
# value text, not because the key is related.
