Subject: [PATCH 3/3] checkpatch: add 6 missing types to --list-types

Unlike all other types, LONG_LINE, LONG_LINE_COMMENT and
LONG_LINE_STRING are passed to WARN() through a variable. This causes
the parser in list_types() to miss them and consequently they are not
present in the output of --list-types.

Additionally, types TYPO_SPELLING, FSF_MAILING_ADDRESS and AVOID_BUG
are passed with a variable level, causing the parser to miss them
too.

So modify the regex to also catch these special cases.
