[Help-source-highlight] [patch] highlighting usertypes started with `_'

[Masatake YAMATO]

Hi,

In C program usertypes started with `_' are not highlighted expectedly.
e.g.

    typedef i __i;
    __i j = 1;

here __i is not recognized as usertype.
Usetype started with _ is popular in linux kernel.
