That is the problem X.

That is your idea of a solution, Y.
You have XY problem. You need to do X, and you think you can use Y to
do X, so you ask about how to do Y.
If you want to list all revsions between v1.0-a and master, use
git rev-list v1.0a..master
or
git rev-list --ancestry-path v1.0a..master
depending on definition of _between_ (see "History simplification" in
git-log(1) manpage for description of `--ancestry-path` option).
