Fix divide by zero when downloading zero length files
If someone did a 'touch bogusrepo.db', we had the potential to throw a SIGFPE or divide by zero, given that the total file size was 0 and getting passed up to the pacman callback. Fix this so we get weird but sane output and don't blow up when downloading: :: Synchronizing package databases... core 35.7K 306.7K/s 00:00:00 [###################] 100% bogusrepo 0.0K 0.0K/s 00:00:00 [###################] 100% Exception as seen in gdb: Program received signal SIGFPE, Arithmetic exception. 0x000000000040cc73 in cb_dl_progress (filename=0x619dfc "bogusrepo.db", file_xfered=0, file_total=0) at callback.c:584 584 file_percent = (file_xfered * 100) / file_total; Signed-off-by: Dan McGee <dan@archlinux.org>
