				# Given a Subversion commit log on stdin, extract the PR numbers
				# and print them on a single line to stdout.
				#
				# The recommended form is:
				#
				# PR: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=123456
				#
				# Bare PR numbers are also accepted, multiple per line, with optional commas.
				# A commit log can have multiple "PR:" lines.
				# Specifically, any whitespace-delimited field that is entirely numeric
				# (with an optional trailing comma) is considered a PR number.
				# Other text is ignored. See tests/test_extract_pr_numbers.py for examples.
