I meant what I said.  The 'ARB extensions ...' comments are placeholders
for extensions that are not there.  Previously only 154 was there, hence
the 149-153 and 155-159.  You're adding 153, so those become 149-152 and
155-159.

Looking at this more closely... there are some other errors here
unrelated to your change.  I know we support
GL_ARB_texture_mirror_clamp_to_edge (extension #149),
GL_ARB_texture_stencil8 (extension #150), and
GL_ARB_vertex_type_10f_11f_11f_rev (extension #151).  I think these are
all extensions that just enable pre-existing enums in new places, so
they don't add anything new for this file.  A reasonable follow-up patch
would be to add blocks for these extensions like the existing
GL_ARB_texture_non_power_of_two block:

<category name="GL_ARB_texture_mirror_clamp_to_edge" number="149">
    <!-- No new functions, types, enums. -->
</category>

It may not be worth the effort.
