It seems that there are four changes in your patch.

1. Use of flag table (gtags-flag-table)

        It's smart. But thinking about the work of debugging,
        I am hesitant to take it.

        There is a merit of using flag value itself directly.
        Because the flag value is equal to the flag value of
        the command line of global(1) except for "C"(--from-here=<...>).
        Understanding the flag value, what should be done is clear.

2. Small changes of display

        o Change the name of [GTAGS SELECT MODE] page from '...(R)' to 
'...(Ref)'.
        o Change the message "Searching <tag name> ..." to "!!!!! ...".

        Are these necessary? (for debugging?)

3. Asynchronous searching

        It's great.

        Since some people dislike asynchronous behavior, I would like to use
        custom variable.

        (setq gtags-mode-hook
          '(lambda ()
            (setq gtags-asynchronous-search t)
        ))

4. Adding local flag to each interactive functions

        How to use this facility?
        Which range is local?

If possible, would you please write a change in a patch?
Generally, it is difficult to apply the patch which contains many changes
which are not mutually related.
Anyway, thank you!
