Hi,

gFTP currently uses the LIST command to retrieve directory contents, but appends to it non-standard "parameters", such as -aL: this breaks those servers that abide by the letter of the RFC and stops working on all the other servers the moment a file/directory named "-aL" exists in the current working directory. gFTP should probably at least retry to issue LIST without the appended "-aL" options, when that command fails.

However, most of the FTP servers nowadays support the MLSD command, standardized by RFC 3659, and I believe gFTP should use that for directory listing, only falling back to LIST if MLSD is not supported.
