It seems that the logging message of gtags -vi has been changed.
Is the change needed?

About the change in the specification, I think that it is necessary to
discuss it separating from the tuning, and it should be decided by user's
aspect not by programmer's one. I think that the new logging message is
long and is not easy to understand.

I invoked gtags -vi like follows:
% gtags
% touch libutil/strbuf.c
% cp libutil/strbuf.c libutil/add.c
% rm libutil/strbuf.h
% gtags -vi
... Logging message...
