Use a format string for errmsg() of literal
Use a format string for errmsg() of literal

Using the string literal in errmsg directly without a format string
triggers warnings in clang under -Wformat-security. Use a simple
format string containing just a reference to the string literal to
avoid warnings and possibly hiding bugs.
