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.
