Embedded new lines aren't interpreted correctly in markdown renderers (they are treated as preformatted text instead). I removed the embedded newlines in the docker image spec.

Mostly, they always have been. Most regular expressions were implemented
as `[\w][\w.-]{0,127]`, which actually allows 128 characters, since we
start with a character in the first expression.
This "fact" has been backported to the existing specifications where
length is mentioned. For the most part, no ill-effects should come of
this, unless someone has optimized to hold the length of a tag in a 7
bit integer.
