Update to 1.11.4:

* Changes in Wget 1.11.4

** Fixed an issue (apparently a regression) where -O would refuse to
download when -nc was given, even though the file didn't exist.

** Fixed a situation where Wget could abort with --continue if the
remote server gives a content-length of zero when the file exists
locally with content.

** Fixed a crash on some systems, due to Wget casting a pointer-to-long
to a pointer-to-time_t.

** Translation updates for Catalan.
