The syntax overview no longer describes a line-based format, since that
is not what the rest of the documentation shows. It now covers the
grammar, the two naming conventions, the nine aliases, and the leading
'-' on a path, and it says plainly that both formats are still read and
told apart per file by content. Without that, a reader with an
existing configuration is left wondering what happened to it.
service-opts.md was a list of modifiers to place between a directive
and its command, so it needed rewriting rather than translating: there
are no positions left to describe. It is now grouped by what the
settings do.
conditions.md needed correcting. It presented '!' as a condition
prefix alongside '~'. It is neither a condition nor a negation, it is
a flag on the block that means one thing on a service and another on a
run or task, so it is spelled reload-signal and required here, and the
page maps the old form to both.
Two things the pages claimed are not true. The kill delay range is
1-300, not 1-60, and stop and reload scripts are no longer run without
a timeout.
ChangeLog.md keeps its line-based examples. Those sit in historical
release entries, and rewriting them in a syntax that did not exist at
the time would misdate the format.

The PTY approach caused isatty() to return true for services using
the log directive, triggering programs like fprintd (using glib) to
emit ANSI escape codes and other TTY-specific formatting in syslog.
Using a standard pipe ensures isatty() correctly returns false, so
programs produce plain text output suitable for logging.
For services that require line-buffered output, users can wrap the
command with `stdbuf -oL` as documented in doc/config/logging.md.
Fixes#455
