Add support for --revision option

kpruden · kpruden · commit cf63ff356e1f · 2010-11-08T21:09:59.000-08:00
Support the --revision REV argument, which allows the user to restrict the set
of svn revisions pulled during the initial clone.  This argument is passed
directly to the 'git svn clone' command.  This option is ignore if the --rebase
option is specified.
