Improve commandline hints

[elsapo]

​http://filezilla.sourceforge.net/cmdline.htm

Underneath:

-u <sourcefile> <targetdir>

Add this:

Note that sourcefile must contain at least one backslash

This is due to the parsing code in MainFrm.cpp, circa
line 2449 (in current CVS) in method
CMainFrame::OnProcessCmdLine:

int pos=localfile.ReverseFind('
');

if (pos==-1

!pos

pos==(localfile.GetLength()-1))

AfxMessageBox(IDS_ERRORMSG_CANTPARSECMDLINE);

(This is really not intuitive, and I had to debug the
code to figure out why it was telling me that it could
not parse the commandline.)
