Hashes in gathered links may contain leading newlines

[rodrigogiraoserrao]

Hey Simon, all but the first hash per tool has a leading newline here:

tools/gather_links.py

Line 38 in 8152f0b

commit_hash = raw_commit[:first_pipe]

The colophon page thus ends up having the HTML “broken” in the commit hash URLs because of the leading newlines, although browsers don't seem to be fazed by it. I did have an issue with these newlines in the middle of URLs, though, and ended up fixing it with a plain call to .strip():

commit_hash = raw_commit[:first_pipe].strip()

Thought you might like to know since these extra newlines might bite you later down the road.
