$ fossil pull
...
</pre>

At this point, I have looked at the timelines from my clone repository
and side by side in the browser and seen exactly
the difference described.

<pre>
fossil export ticket emjtkt
fossil config pull ticket
...
$ fossil config export ticket drhtkt
</pre>

On refreshing pages in the browser, they now look identical.

Looking at the export files, there are lots of differences, but in
particular, I had

<pre>REPLACE INTO config VALUES('ticket-closed-expr','status=''Closed''');</pre>

while the pulled config has

<pre>REPLACE INTO config VALUES('ticket-closed-expr','status=''Closed'' OR status=''Fixed''');</pre>

The former is specified as the default in tktsetup.c and wikiformat.c, so I feel quite justified closing this as "Not A Bug".
