[Bug-wget] How to set -l to be zero? (Or how to download a single webpage and convert the absolute links to relative links with wget?)

[Peng Yu]

I need to use the option --convert-links to download only one webpage,
because I want to convert absolute links to relative links if the
links are under the host directory where the webpage is in. Since I
only interest in one page, I'd like to set -l be zero. But it seems
that if I set it to zero, wget will download everything linked from
this webpage.

Is there a way to download a single webpage and convert the absolute
links to relative links with wget?
