automatically trimming file name for downloading

[aukfilezilla]

fileZilla can not transfer file which name has space in the beginning. In downloading scenario, fileZilla will trim the file name first, then request it from server. Server will simply return 550 Failed to open file(in my case is vsftpd).

I can download the same file with space in the beginning of the file name using ftp(0.17-23). the fileZilla version is 3.3.5.1, build date is 2010-12-11

Please note not all files which name contains space in the beginning fail to download. For example, .swf file can be downloaded. but .txt, .jpg, .png file will reproduce the error
