[issue18671] enhance formatting in logging package

[M. Dietrich]

M. Dietrich added the comment:

for a logging library the important thing would be to not loose the information that was meant to log. as i said i do alot of long-running huge-data-processing scripts in py using the library. if the logging breaks but doesnt log what was intended to log i judge this a major problem. and furthermore: it is so simple to add both information: the data that was to be logged plus the state that an error occured while formatting and where the log-call was made.
