There is a glitch in the Help Viewer of the G-Code Editor handling comments so that sometimes
the help window remains empty.
Comments can be embedded in a line using parentheses () or for the remainder
of a line using a semi-colon. Unfortunately, comments are not parsed as
whitespace and you have to add extra whitespace to separate commands and comments:
Example:
G28 ; Displays the correct help text
G28; Displays nothing
