fast-export: quote paths in output
Many pathnames in a fast-import stream need to be quoted. In particular: 1. Pathnames at the end of an "M" or "D" line need quoting if they contain a LF or start with double-quote. 2. Pathnames on a "C" or "R" line need quoting as above, but also if they contain spaces. For (1), we weren't quoting at all. For (2), we put double-quotes around the paths to handle spaces, but ignored the possibility that they would need further quoting. This patch checks whether each pathname needs c-style quoting, and uses it. This is slightly overkill for (1), which doesn't actually need to quote many characters that vanilla c-style quoting does. However, it shouldn't hurt, as any implementation needs to be ready to handle quoted strings anyway. In addition to adding a test, we have to tweak a test which blindly assumed that case (2) would always use double-quotes, whether it needed to or not.
