* doc/wget.texi: updated documentation to reflect the new FTPS functionality.
 * src/ftp-basic.c (ftp_greeting): new function to read the server's greeting.
   (ftp_login): greeting code was previously here. Moved to ftp_greeting to
   support FTPS implicit mode.

   (ftp_loop_internal): test for new FTPS error codes.

e4db00d74d Add option to write URL rejections to a tab-delimited CSV log.
* main.c: Add "--rejected-log" option.
 * init.c: Add "rejectedlog" command.
 * options.h: Add "rejected_log" parameter string.
 * wget.texi: Add brief documentation on new --rejected-log option.
 * recur.c: Optionally log details of URLs not traversed.
   Add reject_reason enum.
   (download_child_p -> download_child): Return a reject_reason.
   (descend_redirect_p -> descend_redirect): Return a reject_reason.
   (retrieve_tree): Support logging reasons for rejection.
   Add write_reject_log_header that writes a CSV format header to a file.
   Add write_reject_log_url that writes a url struct to a file in CSV format.

   rejection reason to a CSV file.
 * Test--rejected-log.px: Add a basic test for the --rejected-log command.
 * tests/Makefile.am: Run Test--rejected-log.px.

This allows you to figure out why URLs are being rejected and some context
around it. CSV is used as the output format since it can be used easily parsed,
it's delimited by tabs instead of commas to allow using all (quoted) URL
characters and includes column names which may be used for compatibility.

8705e27e20 progress bar: Allow display on stderr alongwith -o
This commit causes the --show-progress option to print the progress bar
to stderr even when a logfile was explicitly provided on the command
line. Such a combination allows a user to log the output of Wget while
simultaneously keeping track of the download status.

18b0979357 CVE-2014-4877: Arbitrary Symlink Access
Wget was susceptible to a symlink attack which could create arbitrary
files, directories or symbolic links and set their permissions when
retrieving a directory recursively through FTP. This commit changes the
default settings in Wget such that Wget no longer creates local symbolic
links, but rather traverses them and retrieves the pointed-to file in
such a retrieval.

The old behaviour can be attained by passing the --retr-symlinks=no
option to the Wget invokation command.

4eeabffee6 More progress bar aesthetic changes
This commit introduces two new changes to how the progress bar looks:
1. Support the --progress=bar:noscroll option which will prevent the filename
   from scrolling in the progress bar
2. Print human readable value for the amount already downloaded for any file

8c2fd06ba8 Add --show-progress to force display progress bar
This is a relatively large commit that implements two major features:

1. Implement --show-progress switch to force the display of the progress bar in
   any verbosity level
2. Edit the implementation of the progress bar so that the filename is displayed
   in the same line.
