BIP-93 credits its first two authors as a single entry sharing one address:
Authors: Leon Olsson Curr and Pearlwort Sneed <pearlwort@wpsoftware.net>
Andrew Poelstra <andrew.poelstra@gmail.com>
The table row split that entry on a comma, so it reads as three authors with three addresses. buildtable.pl keeps the whole name ahead of each address and joins entries with a comma, so it renders the row as Leon Olsson Curr and Pearlwort Sneed, Andrew Poelstra.
Running scripts/buildtable.pl and diffing against the committed table, this was the only row where the two disagreed on content. With this change the two match everywhere except the BIP number allocated rows for 40, 41 and 63, which have no files for the script to read and are maintained by hand.
scripts/link-format-chk.sh, scripts/buildtable.pl and typos all still pass.
