Subject: [PATCH v4 0/2] kconfig: warn of unhandled characters in Kconfig commands

This patchset changes the lexer file to emit a warning if any unhandled
characters are found in the input. So far, Kconfig options like

 +config FOO
    bool
    [...]

(note the wrong '+'!) were parsed without a warning. As simply adding a
warning for '.' produces lots of warnings as occasionally '---help---'
is used instead of 'help' (and thus '-' is recognized as an unhandled
character), we need to handle '---help---' separately.

Changes to v1:
	- add '---help---' in zconf.gperf instead of special casing
	  it in zconf.l

Changes to v2:
	- Do no constify char parameter to warn_ignored_character
	- Shorten rule definitions for '.'

Changes to v3:
	- spaces -> tabs in zconf.gperf
