In contrast to GIT_SSH, SVN_SSH requires quotes for paths that contain
spaces. As GIT_SSH will not work if it contains quotes, it is safe to
assume it never contains quotes. Also, adding quotes to SVN_SSH for paths
that do not contain spaces does no harm. So we always add quotes when
deriving SVN_SSH from GIT_SSH on msys.

In certain situations it may be necessary to manually remap an svn
repostitory UUID. For example:
o--- [git-svn clone]
/
[origin svn repo]
\
o--- [svnsync clone]
Imagine that only "git-svn clone" and "svnsync clone" are made available
to external users. Furthur, "git-svn clone" contains only trunk, and for
reasons unknown, "svnsync clone" is missing the revision properties that
normally provide the origin svn repo's UUID.
A git user who has cloned the "git-svn clone" repo now wishes to use
git-svn to pull in the missing branches from the "synsync clone" repo.
In order for git-svn to get the history correct for those branches,
it needs to know the origin svn repo's UUID. Hence rewriteUUID.

The old function would have to check all mentioned merge tips, every time

for each listed mergeinfo line. If there are a lot of feature branches
being merged into a trunk, this makes for a very expensive operation for
detecting the new parents on every merge.

When recording the revisions that it has merged, SVN sets the top
revision to be the latest revision in the repository, which is not
necessarily a revision on the branch that is being merged from. When
it is not on the branch, git-svn fails to add the extra parent to
represent the merge because it relies on finding the commit on the
branch that corresponds to the top of the SVN merge range.
In order to correctly handle this case, we look for the maximum
revision less than or equal to the top of the SVN merge range that is
actually on the branch being merged from.

git-svn: add (failing) test for SVN 1.5+ merge with intervening commit
This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo
properties. The problematic case is when there is some commit on an
unrelated branch after the last commit on the merged-from branch.
When SVN records the mergeinfo property, it records the latest
revision in the whole repository, which, in the problematic case, is
not on the branch it is merging from.
To trigger the git-svn bug, we modify t9151 to include two SVN merges,
the second of which has an intervening commit. The SVN dump was
generated using SVN 1.6.6 (on Debian squeeze amd64).

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).

This caused problems with our existing minimize_url logic that

using SVN::Ra::get_latest_revnum. We now call SVN::Ra::get_log
