<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">What is the difference between save() and savePlaylist()? Also, if we don't allow constructor w/out url specified, the url arguments here can go away. (which I'd like very much)
It seems that save() is the public method for other code to use and savePlaylist() is the method for subclasses to implement. If this is the case, make it so:
* make save() non-virtual
* make savePlaylist() protected
In each case, both need to be documented.</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">No, I propose the *other* way around, that url is *always* needed in constructors, and *never* needed in save methods. This also solves some potential problems like overwriting other playlists etc.</pre>

Now that various implementations of file playlists are united, the remote-loading hack in Playlists::loadPlaylistFile() doesn't need to exist anymore (my understanding is that remote loading in Playlists::loadPlaylistFile() existed just to avoid duplication among individual playlist file implementations).
In other words, my view is: if a method accepts KUrl &url (as opposed to QString &filePath), it should obviously handle remote urls.</pre>

I've started my changes with an implementation of a ASXPlaylist class,
due this work I've found that implementation of different playlist file
types has different logic, as result I end up with a rewriting
playlist's implementations.
As example of difference:
-- Constructor M3UPlaylist::M3UPlaylist( const KUrl &url ) sets a url, but
does not load playlist, therefore loading of playlist are
posponed till data from playlist are actualy needed (lazy loading)
On the other hand constructor XSPFPlaylist::XSPFPlaylist( const
KUrl &url, bool autoAppend ) loads playlist.
The main idea of proposed changes is to create a unify code for
processing playlist files:
-- lazy loading through LazyLoadPlaylist
-- common functionality was moved to PlaylistFile.
It is worth to be noticed that this patch changes structure of
playlist's classes, bit does not changes their behavior, even if this behavior
is inconsistent in some cases.
In following patch-requests I plan to submit ASX Playlist parser and
organize playlists processing in more consistent way.</pre>
