[Phpwiki-talk] Tilde inconsistencies

[Matthew P. <mp...@he...>]

Another bug report I've gotten:
http://bugs.debian.org/227953

Basically, ~ out by itself is still a tilde, but in contact with anything
else it's made invisible and will suppress specialness.

Two problems with this:

1) It's inconsistent.  While the rule isn't too hard to follow ("If the
tilde is touching anything, double it to make it display"), it's a PITA. 
I'd be inclined to simplify it to "if you want a tilde, type two".

2) The method to produce a visible tilde is thoroughly undocumented in
TextFormattingRules, as far as I can see.  Hence, discovering the rules is,
pretty much, up to individual experimentation.  See the above-linked bug
report for a demonstration of one person's experimentation in that area.

Do others consider the suppression of tildes when they are not used
immediately prior to a "special" text a bug?  Should the remaining
exceptions be ironed out, or is it all good as-is and should just be
documented?
