Relative links for wget2

[Matt Huszagh]

Hello,

I'm trying to archive a single webpage for offline viewing with
wget2. To accomplish this, I'm invoking the following command:

```
wget2 --robots=off --page-requisites --adjust-extension --convert-links=on 
http://www.ke5fx.com/k22.htm
```

>From reading the help menu, it's my understanding that wget2 should
download everything need to display this page (from page-requisites) and
convert the links to these resources to point to the local copies (with
convert-links).

However, this is not the behavior I observe. For example, the HTML for
several of the images show up as

```
<i>Click on photos below to enlarge</i>
<hr>
<br clear=all>
<a href="http://www.ke5fx.com/k22/ext_large.jpg";><img 
src="http://www.ke5fx.com/k22/ext_sm.jpg"; hspace=30 vspace=30></a>
<br clear=all>
<a href="http://www.ke5fx.com/k22/int_large.jpg";><img 
src="http://www.ke5fx.com/k22/int_sm.jpg"; hspace=30 vspace=30></a> 
<br clear=all>
<a href="http://www.ke5fx.com/k22/bfg_large.jpg";><img 
src="http://www.ke5fx.com/k22/bfg_sm.jpg"; hspace=30 vspace=30></a>
<br clear=all>
<hr>
```

The downloaded directory structure does, however, appear correct:

```
$ tree www.ke5fx.com
www.ke5fx.com
├── k22
│   ├── bfg_sm.jpg
│   ├── compare.png
│   ├── ext_sm.jpg
│   ├── HP_k22_s21_s12.gif
│   ├── int_sm.jpg
│   ├── k22_s11.png
│   └── k22_s21_s12.gif
└── k22.htm.html
```

Moreover, doing the same thing with wget works as I'd expect:

```
wget -e --robots=off --page-requisites --adjust-extension --convert-links 
http://www.ke5fx.com/k22.htm
```

```
<hr>
<br clear=all>
<a href="http://www.ke5fx.com/k22/ext_large.jpg";><img src="k22/ext_sm.jpg" 
hspace=30 vspace=30></a>
<br clear=all>
<a href="http://www.ke5fx.com/k22/int_large.jpg";><img src="k22/int_sm.jpg" 
hspace=30 vspace=30></a> 
<br clear=all>
<a href="http://www.ke5fx.com/k22/bfg_large.jpg";><img src="k22/bfg_sm.jpg" 
hspace=30 vspace=30></a>
<br clear=all>
<hr>
```

When I attempt the same wget2 command with a wikipedia page, I get
different results:

```
wget2 --robots=off --page-requisites --adjust-extension --convert-links=on 
https://en.wikipedia.org/wiki/EPROM
```

```
<div class="thumb tleft"><div class="thumbinner" style="width:252px;"><a

class="thumbcaption"><div class="magnify"><a href="/wiki/File:Eprom.jpg"

earliest EPROM types (1971), 256 by 8 bit. The small quartz window admits UV 
light for erasure.</div></div></div>
```

Rather than the src pointing to a remote url or local file, it points to
a nonexistant "//upload.wikimedia.org/...".

It's worth mentioning that wget doesn't get me the expected behavior
here either. The image files reference remote urls, rather than local
paths.

Am I misusing wget2 somehow? If so, what are the correct flags to
achieve what I want?

Thanks
Matt
