[pmwiki-users] "Save as draft" capability

[Patrick R. Michaud]

I've just added a "Save as draft" capability to the Test group
on pmwiki.org -- feel free to experiment with it and let me
know if there are any difficulties.

Here's how it works from an author perspective:  When drafts
are enabled, a "Save as draft" button appears in the list of
buttons.  Pressing this button causes the current text to be
saved to a page that has "-Draft" added to the end (customizable 
by $DraftSuffix).  

Any subsequent edits of the page will automatically pull up the
-Draft version of the page until the -Draft version is officially
saved back to the original (via the normal "Save" button).

The -Draft version of a page and its original source each keep 
their own histories.  When someone saves a draft back to its
original page (via the "Save" button), all intermediate edits of 
the draft are recorded as a single edit in the original.
The -Draft version is also removed (actually, renamed) at that 
point.

To abandon a draft, simply delete it.

This capability is still somewhat experimental -- while I've
given a fair amount of thought as to how this might interact
with things like edit permissions and simultaneous edits,
I'm still working out all the details for it.  

At the moment I have no idea what sorts of problems might arise 
from combining these draft capabilities with other recipes such 
as comments, pmwe, emacs mode, etc.

Unless we encounter major problems, I expect drafts to be
available in beta23 (but it will be disabled by default in any
event).
