git-svn: Allow deep branch names by supporting multi-globs

Some repositories use a deep branching strategy, such as:

    branches/1.0/1.0.rc1
    branches/1.0/1.0.rc2
    branches/1.0/1.0.rtm
    branches/1.0/1.0.gold

Only allowing a single glob stiffles this.

This change allows for a single glob 'set' to accept this deep
branching strategy.

The ref glob depth must match the branch glob depth.  When using
the -b or -t options for init or clone, this is automatically
done.

For example, using the above branches:

  svn-remote.svn.branches = branches/*/*:refs/remote/*/*

gives the following branch names:

  1.0/1.0.rc1
  1.0/1.0.rc2
  1.0/1.0.rtm
  1.0/1.0.gold

[ew:
  * removed unrelated line-wrapping changes
  * fixed line-wrapping in a few more places
  * removed trailing whitespace
  * fixed bashism in test
  * removed unnecessary httpd startup in test
  * changed copyright on tests to 2008 Marcus Griep
  * added executable permissions to new tests
