  • A +1 comment from me for a reason: This is not only the tightest, most elegant answer, it's also memorable, expandable, and reasonable. The intention of removing comments is not hunting comment characters for sport, but to get rid of verbose section headers, irrelevant option lines and useless white space. This fits the purpose perfectly. A comment after a command/option won't disturb in 99% of cases, the contrary is true: It is helpful to read the output. Commented Oct 14 at 6:35
