The browser is probably going by the (non-standard, de facto standard)
Content-Disposition header. Wget supports this in versions 1.11 and
higher, but in a somewhat experimental fashion. It can result in
significantly less efficient downloads, so you have to explicitly ask
for it with the --content-disposition flag. You can also specify
"content_disposition = on" in your .wgetrc/wget.ini
