The following message is repeatedly printed on my system when using the tool:

grep: warning: ? at start of expression

Also started happening to me with a new server (previously working with grep 3.7). Does not cause any actual issues during archiving I noticed.

Grep:

grep (GNU grep) 3.11
grep -P uses PCRE2 10.42 2022-12-11

I forgot to run the URL list through uniq and I've been getting four of these warnings after every duplicate job submission.

I'm running Arch Linux with wayback-spn-script-git version r94.af5f384-1 from AUR and grep-3.11-1 from official repositories.
