The threee tags `<name>`, `</name>` and `<command>` were frequently used
with a leading space that this removes. The reason this habbit is so
widespread in testcases is probably that they have been copy and pasted.
Hence, fixing them all now might curb this practice from now on.
Closes#12028
The tests 20 and 1322 are using getaddrinfo of libc for resolving. In
eglibc-2.19 there is a memory leakage and invalid free bug which
surfaces in some special circumstances (PF_UNSPEC hint with invalid or
non-existent names). The valgrind runs in testing fail in these
situations.
As the tests 20/1322 are not specific on either protocol (IPv4/IPv6)
this commit changes the hints to IPv4 protocol by passing `--ipv4` flag
on the tests' command line. This prevents the valgrind failures.
are not, due mainly to the lack of support for XML character entities
(e.g. & => & ). This will make it easier to validate test files using
tools like xmllint, as well as edit and view them using XML tools.
