\fBFlatten\fR \fIdelim\fR
Flatten the hierarchy within this Store by substituting the canonical
hierarchy delimiter \fB/\fR with \fIdelim\fR.
This can be useful when the MUA used to access the Store provides
suboptimal handling of hierarchical mailboxes, as is the case with
\fBMutt\fR.
A common choice for the delimiter is \fB.\fR.
