[tex-k] Potential bug in MF: missing output in transcript file & long diagnostics on terminal

[Karl Berry]

Hi Dominik,

    Running MF with `\ show tracingonline; show origin..right; end'

(The equivalent thing happens with TeX.) The issue is that the first
line of input is special -- Knuth wanted to allow
**\arbitrarystuff ... \input foo
and get foo.log as the log file name. (Or the \input foo could even
happen within the \arbitrarystuff.) This means any output that would be
logged before the log file is open gets dumped to the terminal.

Quite a few people have noticed this over the years, so
I added this to the nobug page:

Thanks for the report,
Karl
