I have done rebase for 6.18.02 beta (which is direct predecessor of 6.19.00). For now, the work is done here: $ git clone git://fedorapeople.org/~praiskup/tcsh-rebase-6.19.00
This bug appears to have been reported against 'rawhide' during the Fedora 22 development cycle. Changing version to '22'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora22
