[Bug] [Critical] fatal: ambiguous argument 'HEAD~{some commits count}..HEAD'

[RUVATA]

At attempting of use utility at any count of commits (-c cli parameter → -c 10, -c 15 etc.)

After edit dates in temporary text file - we have error:
for example → at call git redate -c 15 (work dir is clean - it is already verified)
fatal: ambiguous argument 'HEAD~15..HEAD': unknown revision or path not in the working tree.

Conceptual idea of script, and interface for batch change date's as temporary list - is great solution
But, It's a pity that it doesn't work
We had to use other solution https://github.com/kareemaly/git-change-date
