Here should be listed also primarily Tom, not sure if you imported some Doug's
changes and also myself.

You could fix the execution with no / in $1.

I do not see a reason to make such exception although it is Tom's script so it
is more up to him.  I find such a possible request can be considered if it
ever appears.

I did not find too clear from the archives why Tom has removed the script.
I found only
	Re: [patch] gdb-add-index tweaks
	https://sourceware.org/ml/gdb-patches/2010-09/msg00133.html

so IIUC the script still was far from perfect so it was not acceptable for FSF
GDB distribution.  So the newly existing gdb/contrib/ directory seems as an
appropriate place for the script to me.


Thanks,
