Details:
Wget incorrectly parses the FTP listing if filenames have leading spaces.
Given a remote file with a name like ' X' (admittedly unusual but legal in
Linux), Wget incorrectly determines the filename as 'X' from the LIST command,
and hence a RETR for the file fails with '550 Failed to open file' or
similar.
See attached output from Wget, and corresponding .listing file.
Worth noting that WinSCP has the same problem, as may other FTP clients. In
fact filenames like ' X' are not easy to create (without shell access to the
FTP server), so this is probably not a high priority problem.
A suggestion: rather than assume there are no leading spaces in the filename
(the current parsing method), maybe we could look for the directory '..' in
the listing, and use that to note the character position which is the start of
the filename.
