This patch should not change behavior. It typically omits backslashes where they are redundant (e.g., in the string literal "^\$"). In a few places, insert backslashes where they make regular expressions clearer: e.g., replace "^\*" (equivalent to "^*") with "^\\*", which has the same effect as a regular expression. Also, use ‘\ %’ instead of ‘\%’ when avoiding confusion with SCCS IDs, and similarly use ‘\ $’ instead of ‘\$’ when avoiding confusion with RCS IDs, as that makes it clearer that the backslash is intended.
