Closes #4751.
The original problem is because of unescaped colons, which is included in this PR. However, there are other characters that might cause similar issues, such as backticks and dollar signs. I don't think one would expect something like
$PATH
to be expanded when he or she puts it in a helper string.Added a few test cases for unit testing. I think we should add integration tests for this, i.e., help strings from comments, but I'm not sure how to do it.
