Warning message for multiple --file=xxx option.

[Shigio YAMAGUCHI]

In current CVS version, multiple --file=xxx option for gtags brings
the following warning message:

% gtags --file=o --file=o
Warning: -f(--file) option specified more than once, last value used.

Since adopting last specification is ordinary in UNIX system, I don't
agree such warning message. It is annoying rather than convenience.
For example, using history function of tcsh, we can use the following
command lines:

% gtags --file=a -c             # Let's make tag files using file 'a'.
% !! --file=b                   # Woops! It was mistaken! Again using 'b'.
gtags --file=a -c --file=b
% _

Even if it is necessary, the message should be displayed only when
the -w option is specified, I think.
