(shrug) It could be done, certainly, and without too much trouble.  One
would need to separate out the new remembered-settings fields in
struct _HText, the new HTdocument_settings_changed() function, and the
blurb in mainloop() that calls it.  But I can't imagine you could rally
much support behind such a change.  This sort of setting-sensitive
re-parsing really only makes sense when source caching is active; your
initial reaction to automatically reloading the document from the server
under these conditions is, I imagine, pretty much universal.

No, source caching does not affect the overall caching protocol in any
way; whatever caching logic Lynx has is applied to the cached document
as before, and the attached cached source, if any, is reloaded in the
process of reloading the cached document.
