Hello Peter, Given simple input as follows,
.PRINTSTYLE TYPESET .START .PP Lorem ipsum. .LIST ALPHA .ITEM one .ITEM two .ITEM three .LIST END mom unexpectedly typeset nr #LIST_INDENT1 21600 appended at the paragraph. I dug in the om.tmac of mom 2.1 and found out there's missing period before nr request at line 15243: . if '\\*[$LIST_ARG_1]'ALPHA' nr #LIST_INDENT\\n[#DEPTH] \ While in mom 2.0-a it's at line 11133: .if '\\*[$LIST_ARG_1]'ALPHA' nr #LIST_INDENT\\n[#DEPTH] \ Putting a period before the nr cures the bug. Tested on groff 1.22.2 with mom 2.0-a and 2.1. -- Best regards, Ellam ByDefault
