Previously, the <link lines in HTML are allowed to have longer than 80 characters.
This CL adds <g and <path to the HTML lines that may have unlimited characters.
(These g and path tags are used in svg image data).
These HTML exemptions also have a trailing space. The space is intended to reduce
false-positives in matching. There are some occurrences of these tags followed by a 
\n which will not match (but the line ends there, so it's not an issue).

These new tags may be preceded by blank space so .lstrip() was added to
the test. I believe this .lstrip() should not be an issue for the other
languages and exemptions present.

Bug: None
