Description

If the spec text contains CRLF in a structured header, ecmarkup reports an expected parameter name warning for any parameters. Changing all CRLF characters to LF makes the warning go away, however not supporting CRLF is problematic for Windows users.

Research direction

Start by reproducing the warning with a structured header containing CRLF line terminators, then trace the structured-header parsing entry point. Done means CRLF input no longer produces the expected parameter name warning while LF input continues to work.
