only \r\n, not .*. The test can pass .* as the last thing in $pattern if that is what it wants. In addition to providing this flexibility, this change should speed up pattern matching in cases where the pattern already ended with .* (there were a number of them). This change also helps catch bad patterns--in the old scheme the typo "char \*" instead of "char \\*" would pass. Now it is caught. * Many .exp files: Update callers.
