kconfig: warn of unhandled characters in Kconfig commands
In Kconfig, definitions of options take the following form: "<COMMAND> <PARAM> <PARAM> ...". COMMANDs and PARAMs are treated slightly different by the underlying parser. While commit 2e0d737fc76f ("kconfig: don't silently ignore unhandled characters") introduced a warning for unsupported characters around PARAMs, it does not cover situations where a COMMAND has additional characters before it. This change makes Kconfig emit a warning if superfluous characters are found before COMMANDs. As the 'help' statement sometimes is written as '---help---', the '-' character would now also be regarded as unhandled and generate a warning. To avoid that, '-' is added to the list of allowed characters, and the token '---help---' is included in the zconf.gperf file.
