Subject: git-svnimport.perl: copying directory from original SVN place
X-Git-Tag: v1.4.4-rc1~93^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=83936a29e275bc0c04f60d3333e4951a9e16b1fc;p=git.git

git-svnimport.perl: copying directory from original SVN place

When copying whole directory, if source directory is not in already
imported tree, try to get it from original SVN location. This happens
when source directory is not matched by provided 'trunk' and/or
'tags/branches' templates or when it is not part of specified SVN
sub-project.
