From 580a7aed748ec80ac43781add5df9a7ff6d1dd45 Mon Sep 17 00:00:00 2001 From: Jonathan Nieder Date: Fri, 26 Sep 2014 22:21:16 +0800 Subject: [MAN] Clarify "trap '' signals" syntax in manual page When the manpage states | may be null, which cause the specified signals to be ignored. it is not immediately obvious what it means for an action to be null. Clarify by explicitly referring to an empty string, as opposed to a NULL pointer or the string "null".
