Replace LF with CR/LF while transfer from ftp through squid

[Alexey Roslyakov <squid@xxxxxxxx>]

Hello,
when download text files from ftp-server without proxy - all fine, but 
when using proxy all LF changed to CR/LF ("0x0a" to "0x0d 0x0a" in hex).
There are configuration issue of squid or misconfigured ftp?
Used squid version 2.7, 3.2 and 3.3 from ports on FreeBSD 8.4, 9.1 with 
default configuration.
