[suggestion] Fail cherry-pick if it overwrites untracked files with the matching file names

Hello there,

I have filled a bug-report and it is available at
https://github.com/rupinderjeet/git-cherry-pick-removes-untracked-files

Since your email only receives plain-text, I assume I can't send the
report by uploading it in this email. If there's something I can do
from my end, or if you need some more information, please let me know.

From,
Rupinderjeet Singh Hans.
