 *

 *      but user can pick any inventory letter (including 'from').
 *
 *  to == from, 'from' has a name
 *      All compatible items (same name or no name) are gathered
 *      into the 'from' stack.  No count is allowed.
 *  to == from, 'from' does not have a name
 *      All compatible items without a name are gathered into the
 *      'from' stack.  No count is allowed.  Compatible stacks with
 *      names are left as-is.
 *  to != from, no count
 *      Move 'from' to 'to'.  If 'to' is not empty, merge 'from'
 *      into it if possible, otherwise swap it with the 'from' slot.
 *  to != from, count given
 *      If the user specifies a count when choosing the 'from' slot,
 *      and that count is less than the full size of the stack,
 *      then the stack will be split.  The 'count' portion is moved
 *      to the destination, and the only candidate for merging with
 *      it is the stack already at the 'to' slot, if any.  When the
 *      destination is non-empty but won't merge, whatever is there
 *      will be moved to an open slot; if there isn't any open slot
 *      available, the adjustment attempt fails.
 *
 *      To minimize merging for 'from == to', unnamed stacks will
 *      merge with named 'from' but named ones won't merge with
 *      unnamed 'from'.  Otherwise attempting to collect all unnamed
 *      stacks would lump the first compatible named stack with them
 *      and give them its name.
 *
 *      To maximize merging for 'from != to', compatible stacks will
 *      merge when either lacks a name (or they already have the same
 *      name).  When no count is given and one stack has a name and
 *      the other doesn't, the merged result will have that name.
 *      However, when splitting results in a merger, the name of the
 *      destination overrides that of the source, even if destination
 *      is unnamed and source is named.
