# Get the word to complete
# This is nicer than ${COMP_WORDS[$COMP_CWORD]}, since it handles cases
# where the user is completing in the middle of a word.
# (For example, if the line is "ls foobar",
# and the cursor is here -------->   ^
# it will complete just "foo", not "foobar", which is what the user wants.)
#
# Accepts an optional parameter indicating which characters out of
# $COMP_WORDBREAKS should NOT be considered word breaks. This is useful
# for things like scp where we want to return host:path and not only path.
