git svn: revert default behavior for --minimize-url

This reverts the --minimize-url behavior change that
appeared recently in commit 0b2af45
("Fix branch detection when repository root is inaccessible").

However, we now allow the option to be turned off by allowing
"--no-minimize-url" so people with limited-access setups can
still take advantage of the fix in
0b2af45.

Also document the behavior and default settings of minimize-url
in the manpage for the first time.

This introduces a temporary UI regression to allow t9141 to pass
that will be reverted (fixed) in the next commit.
