Minor output fix to use quote_n() instead of quote()
- src/ftp.c (in ftp_retrieve_list): change quote to quote_n
- src/iri.c (in do_conversion): change quote to quote_n
- src/url.c (in convert_fname): change quote to quote_n
The implementation quote() reuses the buffer it returns which leads to printing the same string for each quote() call in one output line. Instead, quote_n() should be used as highlighted in the doc: https://www.gnu.org/software/gnulib/manual/html_node/Quoting.html
