without a body block. This can even happen for list types that
usually don't have heads in the first place. So even in this
case, check for the existence of the body before accessing it.

that have broken another block, their closure pending until the
end of the broken block. This avoids syntax tree corruption
leading to a NULL pointer access found by jsg@ with afl.

Remove direct calls to printf from the tls_check_hostname() path. This allows
NUL byte error messages to bubble up to the caller, to be logged in a
program-appropriate way. It also removes non-portable calls to getprogname().

Add tests to verify that we get SIGSEGV when passed a NULL src or dst.
It is better to crash than for an implementation to check for NULL

* The first argument of .Pf is not parsed.
* Normal delimiter handling does not apply to the first argument of .Pf.
* Warn if nothing follows a prefix (inspired by groff_mdoc(7)).
* In that case, do not suppress spacing.

Since this was the last remaining FATAL error in this area,
this change will allow major simplifications in the mdoc(7) parser.

1. Correctly parse stray .Ec without preceding .Eo,
avoiding an assertion violation found by jsg@ with afl.
2. Correctly parse .Ec arguments when breaking another block.
3. Correct spacing around closing delimiter when breaking another block.
4. Sync some related formatting control from -Tascii to -Thtml.

Note that two of these tests are using IPv6 addresses and expose another

fixes it.
