From ca2a0798656aa1219c6ff4fa66cd0f3340ddd5be Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Fri, 15 Apr 2005 15:08:09 -0700 Subject: [PATCH] [PATCH] Add "-q" option to show-diff.c This adds the '-q' option for show-diff.c to squelch complaints for missing files. It is handy if you want to run it in the merge temporary directory after running merge-trees with its minimum checkout mode, which is the default, because you would not find any files other than the ones that needs human validation after the merge there. It also fixes the argument parsing bug Paul Mackerras noticed in <16991.42305.118284.139777@cargo.ozlabs.ibm.com> but slightly differently.
