Deactivate passage links

[alexwarren]

One passage might need to deactivate links to another passage.

You can see [a], [b], [c] and [d].

[a]:
@deactivate b
Clicking link A will deactivate the link to B, but C and D are still available.

Imperfect and partial workaround until @deactivate is implemented.
Just in case it is useful for someone wanting to do something like this.

Viewing bbb will deactivate ccc link.
Viewing ccc will deactivate bbb link.

[aaa], {label:bc=[bbb], [ccc]}, [ddd]

[aaa]:
aaa example text

[bbb]:
@replace bc=bbb, ccc
bbb example text

[ccc]:
@replace bc=bbb, ccc
ccc example text

[ddd]:
ddd example text
