Re: vc-fossil to non-gnu elpa?

[Alfred M. Szmidt]

   It seems to build on my system:

           icterid$ make build/vc-fossil
           emacs --batch -l /home/philip/Code/src/nongnu/admin/elpa-admin.el    
\
                    -f elpaa-batch-make-one-package vc-fossil
           Cloning branch vc-fossil:
           +refs/heads/*:refs/remotes/origin/Preparing worktree (new branch 
'elpa/vc-fossil')
           HEAD is now at 7815c30d7 vc-fossil.el: Update from fossil.

   Did you change the history or do you have a local commit with
   "20210928.0.." as a version number?

No, but could it be how the string is constructed?

If that those two parts are missing/empty then you will get 
vc-fossil-20210928.0...tar...
