Can't parse entries containing the "S" permission #223

Open PikeUK opened 6 years ago

The REX_LISTUNIX regex in parser.js for the third character of a file permission group is as follows:

[\\-xstT]

However a directory on a server I'm trying to connect to has the S file mode bit set:

    drwx--S---   7 ftp      ftp          4096 May  2  2017 .\r\n
    drwx--S---   7 ftp      ftp          4096 May  2  2017 ..\r\n
    drwx------   2 ftp      ftp          4096 Apr 27 12:02 cgi-bin\r\n
    -rw-------   1 ftp      ftp             0 Jul  2  2014 .htaccess\r\n
    drwx------   2 ftp      ftp          8192 May  2  2017 logs\r\n
    drwx--S---   5 ftp      ftp          4096 Apr 13 09:39 public\r\n
    drwxr-sr-x   2 ftp      ftp          4096 Mar 10  2014 secure\r\n
    drwx--S---   2 ftp      ftp          4096 May  2  2017 secure-cgi-bin\r\n

This causes those entries to be returned unparsed. I found this problem trying to connect using the sftp extension in VS Code which fails to work at all on the particular server with this issue.

According to the ls manual S is a valid file mode bit which means:

If the set-user-ID or set-group-ID bit is set but the corresponding executable bit is not set.
