* The new security fix in 6.4.20 for CVE-2021-36386 caused truncation of
messages logged to buffered outputs, predominantly --logfile.
This also caused lines in the logfile to run into one another because
the fragment containing the '\n' line-end character was usually lost.
Reason is that on all modern systems (with <stdarg.h> header and vsnprintf()
interface), the length of log message fragments was added up twice, so
that these ended too deep into a freshly allocated buffer, after the '\0'
byte. Unbuffered outputs flushed the fragments right away, which masked the
bug.
