Fix stamp.sh error calling git

[kahlkevin]

• Problem: $1 is empty string inside shell function "timestamps"
• Solution: Use $list global computed previously

[kahlkevin]

Or, instead was the intent that the timestamp match the most recent commit on a per file basis?

If so, I can patch this pull request (or submit a new one) to change $list to $i. Please advise if this is the maintainers' preference.

(Either way, the current $1 is incorrect and leads to error output during make)

Yes, I think $i was intended. Thanks, good catch!

Okay, I've made the change here (via rebase/force-push so we still only have a single commit). It uses $i now, and I agree this seems more likely to have been original intent.

Once you're happy with validation, I look forward to your approval and completion of the pull request.

Merged, thanks!
