Bug 17400 – put a new line before "candidates are:" in error messages

Suggestion: Put a new line or two before "candidates are:", and maybe capitalize it, in the error message for template ambiguity errors. I think they're already hard enough to read, and this might help a little. I made an issue for it, because I don't feel fully qualified to decide on this. Current template error example: file(line): Error: template foo cannot deduce function from argument types !()(int, string), candidates are: file(line): foo(Args...)(auto ref Args arg) if (!anySatisfy!(isString, Args)) Recommended change: file(line): Error: template foo cannot deduce function from argument types !()(int, string) Candidates are: file(line): foo(Args...)(auto ref Args arg) if (!anySatisfy!(isString, Args)) Or (more spacious): file(line): Error: template foo cannot deduce function from argument types !()(int, string) Candidates are: file(line): foo(Args...)(auto ref Args arg) if (!anySatisfy!(isString, Args)) It seems trivial, but little things matter too!
