The below code segment in gtags/gtags.c performs deletion of tags if
are present:

                               if (fid == NULL) {
                                        if (added) {
                                                strbuf_puts0(addlist,
path); <-- We just add and nothing to remove since fid is NULL
                                                total++;
                                        }
                                } else if (added) { <-- If added based
on prefix '+'
                                        strbuf_puts0(addlist, path);
                                        total++;
                                        idset_add(deleteset, n_fid);
<-- we delete the tags on update since fid is not null
                                } else { <-- If deleted based on prefix '-'
                                        strbuf_puts0(deletelist, path);
                                        idset_add(deleteset, n_fid);
                                        total++;
                                }

The tags for the above files exist and the above code snippet handles
the add versus update based on fid.
