Adds a new option which lets you turn off the concept
of a separate maximum comment width from the maximum
line width. By default, comments are limited to 72
characters wide (or more accurately the configured width
for Markdown files), which leads to more readable text.
However, if you really want the full line width to be
used, uncheck the "Allow max comment width to be separate
from line width" setting.
Fixes bug to ensure the line width and max comment width
are properly read from the IDE environment settings.
