# possible matches. Necessary for any partial word completions (vs
# completions performed when no partial words are present).

# $2 is the current word or token being tabbed on, either empty string or a
# partial word, and thus wants to be compgen'd to arrive at some subset of
# our candidate list which actually matches.

# COMPREPLY is the list of valid completions handed back to `complete`.
