Control ASCII Download Line Endings (CrlfMode)

Demonstrates the CrlfMode property, which controls line-ending conversion when downloading in ASCII transfer mode: 0 leaves them as received, 1 converts to CRLF, 2 to LF, and 3 to CR.

Background: When you deliberately download text in ASCII mode, CrlfMode lets you force the saved file's line endings to a specific convention — CRLF for Windows tools, LF for Unix — regardless of what the server sends. It applies only in ASCII mode, so pair it with SetTypeAscii; in the recommended default binary mode, bytes are preserved verbatim and this setting has no effect. Reserve ASCII mode (and this property) for the rare case where line-ending normalization of text is actually wanted.
