Subject: [PATCH 1/6] git svn: fix fetch where glob is on the top-level URL

In cases where the top-level URL we're tracking is the path we
glob against, we can once again track odd repositories that keep
branches/tags at the top level.  This regression was introduced
in commit 6f5748e14cc5bb0a836b649fb8e2d6a5eb166f1d.

Thanks to Daniel Cordero for the original bug report and
bisection.

Subject: [PATCH 3/6] git-svn: allow test setup script to support PERL env. var

Possibly the 'perl' in the PATH is not the one to be used for the tests;
let PERL set in the environment select it.

Subject: [PATCH 4/6] git-svn: convert SVK merge tickets to extra parents

SVK is a simple case to start with, as its idea of merge parents
matches git's one.  When a svk:merge ticket is encountered, check each
of the listed merged revisions to see if they are in the history of
this commit; if not, then we have encountered a merge - record it.

[ew: minor formatting cleanups]

Subject: [PATCH 5/6] git-svn: add test data for SVN 1.5+ merge, with script.

Dump generated with SVN 1.5.1 (on lenny amd64).  This test
should hopefully cover all but a few intermediate versions of
the svnmerge.py script.

From dff589ef949e97cbec5363b105ba27f6e85594fb Mon Sep 17 00:00:00 2001

Subject: [PATCH 6/6] git-svn: convert SVN 1.5+ / svnmerge.py svn:mergeinfo
 props to parents

This feature is long overdue; convert SVN's merge representation to git's
as revisions are imported.  This works by converting the list of revisions
in each line of the svn:mergeinfo into git revision ranges, and then
checking the latest of each of these revision ranges for A) being new and
B) now being completely merged.
