Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
* src/ftpclient.c (connect_to_server): Added support for IPv6. This meant changing from using the PORT command to using EPRT, when setting up the data connection. EPRT is protocol independant. * tests/ftpclient1.c (ftp_test): Added tests which use IPv6 addresses. Fixed a few minor bugs with format strings. * doc/ftpclient.sgml: Mention we support IPv6 and DNS.
