Setting: URLM_WGET_DL_DIR (default: ~) [*]

This is where files downloaded with wget will be saved. Tilde expansion
is supported. If this directory does not exist, it will be created by
wget, when it is run for the first time.

[*] Normally, the log file and download directory should be an absolute
path, or relative to $HOME (with ~ expansion). If a relative path is
used (without ~), it will be resolved relative to the working directory
where irssi was started.

FIXME: this setting may not contain whitespace characters (spaces or tabs).
