store: encode trailing period and space on directory names (issue1417) Windows won't create directories with names ending in period or space, so we encode the last period/space character in directory names of non-hashed paths in the store using reversible ~xx encoding (' ' -> '~20', '.' -> '~2e'). With this change it is possible to remove a directory ending in period or space that was inadvertantly checked in on a linux system while still being able to clone such a repository with its full history to Windows (see also issue793).
