Yes, I outlined that two step process. This is what I do with conventional
version control and this is what I suspect I will be doing a lot with darcs
as well (see below).
You're assumption is that you can get away with
"darcs diff --from-match='...some text...'" directly without having to grep
the change log for a sepecific change and get a unique identifier (currently
its date). And when there's enough unambiguous information to do that its

Yes, sometimes you can just use a number or other convient unique identifier
in the change description and simply search for that. Its pretty neat that
darcs lets you do this in one step. But there are many times you cannot.
What if the identifier is not unique? For example, what if there were
several patches to resolve RT#266?
What if there is no convenient identifier? Skimming through the darcs
change log most of the changes do not have an RT ticket number or anything
else to identify them.
In those cases you're back to the two step process. Grep the change log
for your change, enter the identifier into diff (or whatever). In these
cases its nice to have a simple identifier in addition to darcs' patch
