From: Johannes Schindelin Date: Fri, 9 Nov 2007 11:34:07 +0000 (+0000) Subject: builtin-blame: set up the work_tree before the first file access X-Git-Tag: v1.5.4-rc0~237 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=354e6534c1569d0d23937add8e7b55bf87bbaf20;p=git.git builtin-blame: set up the work_tree before the first file access We check in cmd_blame() if the specified path is there, but we failed to set up the working tree before that. While at it, make setup_work_tree() just return if it was run before.
