From 314d9ea5a3bc60ec518e314bb0bf8072123dc08f Mon Sep 17 00:00:00 2001 From: Natanael Copa Date: Sat, 29 Nov 2008 21:49:07 -0800 Subject: Set prefix in snapshots when using dwimmery This patch sets the directory prefix in archives to be the filename, excluding the suffix (.tar.gz, .tar.bz2 etc). The patch also removes the prefix parameter in cgit_print_snapshot() as the prefix might differ.
