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.

SVK is a simple case to start with, as its idea of merge parents

of the listed merged revisions to see if they are in the history of

And then unescape them when writing to $GIT_CONFIG.
SVN has different rules for repository URLs (usually the root)
and for paths within that repository (below the HTTP layer).
Thus, for the request URI path at the HTTP level, the URI needs
to be encoded. However, in the body of the HTTP request (the
with underlying SVN XML protocol), those paths should not be
URI-encoded[1]. For non-HTTP(S) requests, SVN appears to be
more flexible and will except weird characters in the URL as
well as URI-encoded ones.
Since users are used to using URLs being entirely URI-encoded,
git svn will now attempt to unescape the path portion of URLs
while leaving the actual repository URL untouched.
This change will be reflected in newly-created $GIT_CONFIG files
only. This allows users to switch between svn(+ssh)://, file://
and http(s):// urls without changing the fetch/branches/tags
config keys. This won't affect existing imports at all (since
things didn't work before this commit anyways), and will allow
users to force escaping into repository paths that look like
they're escaped (but are not).
Thanks to Mike Smullin for the original bug report and Björn
Steinbrink for summarizing it into testable cases for me.

In addition to path-based restrictions, Subversion servers over
http(s) may have access controls implemented via the LimitExcept
directive in Apache. In some cases, LimitExcept may be
(arguably) misconfigured to not allow REPORT requests while
allowing OPTIONS and PROPFIND.
This caused problems with our existing minimize_url logic that
only issued OPTIONS and PROPFIND requests when connecting and
using SVN::Ra::get_latest_revnum. We now call SVN::Ra::get_log
if get_latest_revnum succeeds, resulting in a REPORT request
being sent. This will increase our chances of tripping access
controls before we start attempting to fetch history.

Relying on SVN::Core::INVALID_REVNUM (-1) as the "start"

For the case of multiple projects sharing a single SVN repository, it is
common practice to create the standard SVN directory layout within a
subdirectory for each project. In such setups, access control is often
used to limit what projects a given user may access. git-svn failed to
detect branches (e.g. when passing --stdlayout to clone) because it
relied on having access to the root directory in the repository. This
patch solves this problem by making git-svn use paths relative to the
given repository URL instead of the repository root.

This enables git-svn.perl to read multiple 'branches' and 'tags' entries in
svn-remote config sections. The init and clone subcommands also support
multiple --branches and --tags arguments.
The branch (and tag) subcommand gets a new argument: --destination (or -d).
This argument is required if there are multiple branches (or tags) entries
configured for the remote Subversion repository. The argument's value
specifies which branch (or tag) path to use to create the branch (or tag).
The specified value must match the left side (without wildcards) of one of
the branches (or tags) refspecs in the svn-remote's config.

'git svn dcommit' takes an optional revision argument, but the meaning
of it was rather scary. It completely ignored the current state of
the HEAD, only looking at the revisions between SVN and $rev. If HEAD
was attached to $branch, the branch lost all commits $rev..$branch in
the process.
Considering that 'git svn dcommit HEAD^' has the intuitive meaning
"dcommit all changes on my branch except the last one", we change the
meaning of the revision argument. git-svn temporarily checks out $rev
for its work, meaning that
* if a branch is specified, that branch (_not_ the HEAD) is rebased as
part of the dcommit,
* if some other revision is specified, as in the example, all work
happens on a detached HEAD and no branch is affected.

Add a new option, --authors-prog, to git-svn that allows a more flexible
alternative (or supplement) to --authors-file. This allows more
advanced username operations than the authors file will allow. For
example, one may look up Subversion users via LDAP, or may generate the
name and email address from the Subversion username.
Notes:
* If both --authors-name and --authors-prog are given, the former is
tried first, falling back to the later.
* The program is called once per unique SVN username, and the result is
cached.
* The command-line argument must be the path to a program, not a generic
shell command line. The absolute path to this program is taken at
startup since the git-svn script changes directory during operation.
* The option is not enabled for `git svn log'.
