In the current git head version of gschem the page manager sometimes drops entries when navigating a hierarchy.

This is a regression. Traditionally, the page manager used to remember all pages until they are explicitely closed. This came handy when working with a hierarchy.

To reproduce:
1) open the top page of the example in geda-gaf/examples/gTAG/gTAG.sch in gschem
2) open page manager ([P M])
3) select sub sheet symbol "gTAG-psu"
4) go down Schematics ([shift+H S])
5) go up ([shift+H U])
6) select "gTAG-jtagio.sch"
7) go down Schematics ([shift+H S])

expected outcome:
 The page manager adds the entry "gTAG-jtagio.sch" to the tree of pages

actual outcome:
 The page manager drops the entry "gTAG-psu.sch" and replaces it with "gTAG-jtagio.sch"

There other ways to get similar misbehaviour. I found no general rule. Sometimes pages are dropped, sometimes they persist in the page manager.
