Without this patch "git commit file.c file2.c" produces the not so stellar output: error: pathspec 'file.c' did not match any. error: pathspec 'file2.c' did not match any. With this patch, the output is changed to: error: pathspec 'file.c' did not match any file(s) known to git. error: pathspec 'file2.c' did not match any file(s) known to git. Did you forget to 'git add'? Signed-off-by: Andreas Ericsson <ae@op5.se> Signed-off-by: Junio C Hamano <junkio@cox.net>
