See line 882 of mod_dav_svn/repos.c. The root_path will *not* have a
trailing slash, unless it equals "/". So yes, the header comment should be
updated with the additional information.

[efficiency nit]
The path is guaranteed to at least be one character long, and have a leading
slash. Thus, the strcmp() against "/" is overkill. The test can be written
as:
if (root_path[1] == '\0')

No. mod_dav removes the trailing slash in mod_dav.c::dav_create_dir_config()
