Martin Grenfell da3874cf93 fix a bug when opening files in a new tab ... On bufleave we save the nerdtree window state. However, sometimes when bufleave is triggered the tree is no longer open in this tab - e.g. for secondary trees or mappings that open in another tab. Dont bother saving screen state in these cases as the code doing the saving assumes the tree is available in this tab.		2015-05-04 20:25:43 +01:00
