Backward-compatibility *IS* a real consideration.

Still — I can't help wondering if it's much more of a consideration than my 
syntactical hangup about --- having two different meanings.  *ARE* there 
that many existing TiddlyWikis out there with three-hyphen <hr/>s that 
would suddenly become m-dashes?  (I have no idea, but maybe folks will show 
up testifying to how much of a pain it would be for their TWs.)  The 
worst-case scenario seems to be limited inconvenience, with the long-term 
result that TiddlyWiki would have exclusive syntax for <hr/> (*----*) and 
for — (*---*).

The upgrader might even be able to handle a replacement as simple as *^-{3}*
$ *=>* *----* as part of the upgrade process.  (Of course, suggesting that 
could be throwing wide the doors to all sorts of user-code cleanup Jeremy 
wants no truck with.)

Food for thought, certainly.  I definitely appreciated your insights in the 
GitHub threads you linked to, Mario.  (Thanks!)

I remember some of the early discussions about strikethrough, but I 
wandered off for a long while and missed *--* and *---* being incorporated 
(and parsed better in TW5 than they had been in TWC).  I bring it up here, 
in part, because I feel a little guilty for missing the chance to fight for 
the oddball outlying use case of *---* on its own line back when the new 
wikitext syntax was taking shape.

(Wasn't there a suggestion at one point to use some number of *=* 
characters to build an <hr/>?  Or am I misremembering that?  It could be 
that was suggested as a possible strikethrough syntax at some point.)

Wouldn't be the first time!  :-D

I realize I probably sound a tad crazy fretting over this one, and I very 
much appreciate the feedback.  I'd love to hear from others who've tripped 
over the current syntax or whose TWs would take a hit from making such a 
nitpicky change this late in the game.
