Patch from Nuke.YKT to fix a TROR in Polymost issue
Report by oasiz: It only occurs when you try to sandwich surfaces and kind of punch through. It seems similar to the kind of behavior that the pre-TROR fixes did (where you had to stand on the TROR sector for things to work). This seems to work if the weird wall is punching IN on your sector but not OUT to another. git-svn-id: https://svn.eduke32.com/eduke32@7492 1a8010ca-5511-0410-912e-c29ae57300e0
