Sorry for the confusion. The terminal settings are associated with an
fd, which maps more or less to a port, and I thought that you were
opposed to port-specific properties. (Incidentally I did not think that
argument made much sense.)
Having it be a repl-specific property has the irritation of propagating
the width down to nested repls. To me the true place of this setting
is specific to a thread, as repls are (largely) specific to threads.
So it would be equivalent to have `terminal-width' close over a fluid
instead of a lexical.
Anyway, with a week gone by and no more patches from anyone involved, I
decided to think about it myself for a bit, and ended up thinking Mike's
patch was "worse is better", but then also feeling it could be cleaner,
hence my addition.
Also, I wanted the initial settings to reflect the terminal width
without a need to call ,width.
So them's the reasons! Let me know if you have any more concerns. Do
try out different approaches -- it is a clarifying agent :)
Regards,
Andy
