# make does, i.e., considering the next line as a continuation of the
# comment.
#
# - Automake should allow backslash-escaped '#' characters at the end
# of a line (in variable definitions as well as well as in recipes),
# because GNU make allows that.
#
# - GNU make handles comments following trailing backslashes gracefully,
# so Automake should do the same.
#
# - Automake should not complain if the Makefile ands with a backslash
# and newline sequence, because GNU make handles that gracefully.
