Whenever <<loadTiddlers>> is processed, the entire remote file is read-
in and it's tiddlers are compared with the tiddlers in the current
document.  As such, nearly all of the processing overhead occurs *each
and every time* the macro is invoked, regardless of whether or not the
tiddlers in the current document are 'up-to-date'.  Thus, auto-saving
after updating will *not* result in any significant speed enhancement
for subsequent users of that document.

In addition, I really don't like the idea of *automatically*
overwriting the file immediately after *automatically* replacing some
of the tiddlers in the document.  Inasmuch as <<loadTiddlers>>
processing has minimal user interaction, you might not notice which
tiddlers are being replaced during the import.  Sure, a backup file is
usually created when you save the document, but backing out the
updated tiddlers while retaining any other changes you might have made
can be a real hassle and should be avoided whenever possible.  At the
very least, a manual 'save file' action means that the user has a
*chance* to review what was imported *before* overwriting their saved
document.
