You can script this. Provided you have a POSIX-compatible shell (such as
Bash), the encantation would read something like
$ git log --oneline | { n=0; while read line; do printf '%d\t%s\n' $n "$line"; done; }
This is admittedly not convenient so it makes sense to turn into an alias:
[alias]
relog = "!relog() { git log --oneline \"$@\" | { n=0; while read line; do printf 'HEAD~%d\t%s\n' $n \"$line\"; n=$((n+1)); done; }; }; relog"
Then the call
$ git relog
would output something like
HEAD~0 deadbeef Commit message
HEAD~1 fadedfac Another commit message
HEAD~2 12345678 Yet another commit message
...and so on.
It's easy to make that script not output "~0" for the very first entry and
output just "~" instead of "~1" for the second, but I what's presented is
enough for an example.
