Hello Jorg,
If your new URL points to the same path and the same repository (e.g. domain name, port, or protocol
changed), it's enough to update
[svn]
url = YOUR_URL
option and then run
subgit install path/to/repository
to apply the change.
But if you change the URL to an irrelevant URL (e.g. to the URL of another project or to another
path within the same repository), this can lead to an unpredictable behaviour (for the most of the
cases SubGit will detect that the change is not allowed). I think this restriction is reasonable as
changing the URL to an unrelated URL makes no sense.
