[darcs-users] Write-up on "tree repositories" as an alternative to conflictors

[Ben Franksen]

Two minor remarks.

> 4.2.7 Reactivating a patch
> As promised in Section 4.1.3, it is possible to re-activate a previously deactivated patch p. First, it is likely the user will need to de-activate patches p conflicts with, as well as patches that conflict with p’s dependencies if those are also being re-activated. Section 4.2.6 explains how to deactivate these patches and the patches that depend on them.

Obviously, dependencies of p /have/ to be reactivated along with p, so
the "if" is misleading here.

Indeed this should be elaborated!

Cheers
