fortunately it seems this part of linespec is done.

I guess there should have been a ChangeLog for FSF patch reviews compliance
but I am fine with it as is.

I see now the goto is in fact not any win here.
static const char *
remove_tail_spaces (const char *start, const char *s)
{
while (s > start && isspace (s[-1]))
s--;
return s;
}
...
if (name_end (ptr))
return remove_tail_spaces (start, ptr);
So asking for this change if I haven't missed anything and a check-in.
Thanks,
