Tonel: fix possible endless recursion in `TonelRepository class >> discover:` This commit fixes horrible bug in `TonelRepository class >> discover:` when using relative directories that caused endless recursion. This is because `Filename >> directory` does not handle well relative directories: following code causes endless loop: f := '.' asFilename. [ f isRootDirectory ] whileFalse:[f := f directory]. while this one does not: f := Filename currentDirectory. [ f isRootDirectory ] whileFalse:[f := f directory]. Clearly, this is something that has to be fixed in `Filename`, but meanwhile, we fix it here too. While at it, rewrite this method using loop as opposed ro recursion.
