Hi Hari and Paul,
Thank you both for your replies. As you have both reminded me, those
branches and tags aren't ever gone from the repository. I was busy
examining the trees and neglected to see the forest around me.
It hadn't occurred to me that I could copy a directory across repository
revision levels, even though I probably read it somewhere. Now I have
done some experiments and I see that I can delete a tag directory from
the HEAD, but copy it back to the HEAD (at revision+2 from where I
started) by browsing the earlier repository revision and copying from
there. I also see how the command line supports this. I feel much better
about deleting all those old tags and branches now.
Gosh, now I feel like I should clean off my desk too. Clean out the
garage at home. Quit using vim in favor of a squeaky new modern GUI
editor. Well, maybe not the vim thing. ;-)
Thank you both again. Your comments were very helpful.
Best regards,
Rush
P.S. Hari - sorry for the reply just to you. I hit the wrong button.
