While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled
characters") introduced a warning for unsupported characters inside
parameters, it does not cover situations where a statement
has additional characters around it.
This change introduces a warning if superfluous characters are found
around statements. As the 'help' statement sometimes is written as
'---help---', the '-' character would now also be regarded as
unhandled, this change also adds a special rule for this case.
