Comment Delimiters
Use two hyphens (--) to delimit comments within a command line. The comment can
appear anywhere within the command line but cannot be embedded within a word. In
addition, the comment should not contain a semicolon (;). Any part of a comment
following a semicolon is lost because the semicolon causes line termination.
Comments can also appear on their own line when delimited before and, optionally,
after with two hyphens.
