bug#2544: 23.0.60; Could etags please try find a local tag first?

[Matzi Kratzi <matzikratzi@gmail.com>]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Would it make sense, in general, for etags to first try to find a tag
inside the current buffer? I am working in legacy code that has the
same name for certain help functions in many files. I would like etags
to first try find the tag inside the current buffer.

Please consider the following files:

a.c:
#include <stdio.h>

static void help_func (void)
{
  printf ("ad");
}


void a_func (void)
{
 help_func ();
 printf ("a\n");
}

a.h:
void a_func (void);

b.c:
#include <stdio.h>
#include "a.h"

static void help_func (void);

int main (void)
{
  help_func ();
  a_func ();

 return 0;
}

static void help_func (void)
{
  printf ("kalle\n");
}

c:\src\example>C:\download\emacs-cvs\bin\etags a.c a.h b.c

Then go to the line " help_func ();" in b.c and try find-tag. You will
be taken to the function defined in a.c. I know about "C-u M-.", but
that is not a very big help if there is a big number of files with
different help_funcs.

Best Regards
Mats
