Currently, Wikipedia article names are
"case sensitive, but first character must be a capital".
This isn't optimal, because:
* very rarely two things have the same name, only different capitalization
* there is significant group of names thot should be all-lower-case,
like many Unix programs
Fully case sensitive system also wouldn't be optimal.
While it would allow all-lower-case names, it would force many links
to be written as [[Foo|foo]], what would be an unnecessary burder.
So I propose a switch to "case insensitive but case preserving"
system at some point, just like file names on Microsoft Windows.
