The Kconfig language has already been built-in in the latest ctags, so
it would error exit if we try to define it as an user-defined language
via '--langdef=kconfig'. This results that there is no Kconfig tags in
the final tag file. Fix this by skipping the user Kconfig definition for
the latest ctags.

The 'regex' array needs quoting to prevent word splitting/globbing. I 
would suggest to transform 'KCONFIG_ARGS' into an array as well:

KCONFIG_ARGS=()
if ! $1 --list-languages | grep -iq kconfig; then
	setup_regex exuberant kconfig
	KCONFIG_ARGS=(--langdef=kconfig --language-force=kconfig "${regex[@]}")
fi
all_kconfigs | xargs $1 -a "${KCONFIG_ARGS[@]}"

Fair enough.

Sounds great. V2 is coming.
