[igt-dev] [PATCH i-g-t v2 07/19] scripts/igt_doc.py: improve multi-line logic

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

Currently, there's no way to use something like:
	/**
	 ...
	 * Issue:
	 *	https://foo.bar

as https would be mis-interpreted as a field.

Fix it by always requiring one or more spaces/tabs on continuation
lines.
