problem with the removing of glue node in scrp-cjk.lua

[Li Yanrui (李延瑞)]

Hi Hans,

In scrp-cjk.lua, the function "process" can eat some glue node between
CJK glyphs. But the following glue nodes between CJK glyph and
half_width_open/half_width_close glyphs should not be eaten.

For example:

\starttext
中国 (Chinese) 的未来
\stoptext

Its output need stay the same.

Therefore I think the function "process" need add some codes for the
test of half_width_open/half_width_close glyphs. This is a patch for
it.
