I like the way thenosy list is presented with
the key strings instead of the node id. Unfortunately
this was hardcoded in htmlbase.py, so I couldn't
enable the same behaviour for a new multilink
in my issues via html/issue.index.

I have patched it so that instead of comparing
against 'nosy' the showid argument is checked.
The drawback is that this parameter now has
slightly different semantic for links and
multilinks (enable identifier prefix for links,
replace nodeids with keys for multilinks), hasn't it?
Does anyone mind?
