[Ctags] --<LANG>-kinds argument has no effect

[Dmitry G. <dg...@ya...>]

Hi all,

I've tried different different combinations of kinds, but as far as I 
can see, they don't have any effect on the contents on the resulting file.

For example, with these arguments:

ctags -e -o TAGS --ruby-kinds=-c-f-m-F test.rb

I still see all classes and methods in the generated TAGS file.
But if I have that in .ctags and look at "ctags --list-kinds" output, 
all kinds under "Ruby" are marked "[off]".
Same with JavaScript sources. Haven't tested with other languages.

ctags --version:

What am I doing wrong?

Regards,
Dmitry.
