[imp] bug with folder-tree in IMP 4.0-CVS - patch attached

[Michael M Slusarz]

Quoting Jürgen Henge-Ernst <ml at henge-ernst.de>:

| The output of the folders stopped after A.A.A.A, if I expanded all folders.
| The problem seems to be that after the path has been gone to A.A.A.A the
| next-function of IMP_Tree does not find the correct next element in the
| stack, when on the parent level is no further element. If I add a folder
| A.A.B all folders are printed.
|
| A patch is attached which works for me to display all folders, even when
| there are no futher elements to proccess on the parent-level.

Thanks - slightly modified and committed.  Along with my fix for clearing out
the stack array every time we call reset(), hopefully this will (finally) fix
all the folder issues.
