Research direction

No files or tests are identified in the issue. Start by locating the formatting path used when debug.log is overridden and compare it with the stderr path. Done means each instance can choose whether to emit ANSI escape sequences and ISO datetimes independently.

Written by the indexing model from the issue text.

Description

It is possible to redirect the output of some namespaces to files (by assigning a function to debug.log), whilst maintaining others to stderr (by keeping debug.log undefined.)

But all lines are formatted the same way. If stderr is a TTY, they all get colours (using ANSI escape sequences), even in files, and no ISO datetime at the beginning. If stderr is not a TTY (e.g. using 2>&1 | cat) then colours are removed everywhere, even on stderr, and an ISO datetime is prepended to each line.

Is it possible to chose the formatting on a per-instance basis? That is, when I override debug.log, I would like to remove ANSI escape sequences, and add the ISO datetimes.
