bug#35542: Installer does not display full backtrace on error

[Ludovic Courtès]

Hi Mathieu,

Mathieu Othacehe <address@hidden> skribis:

What about instead doing something like this:

  (use-modules ((system repl debug) #:select (terminal-width)))

  (with-fluids ((terminal-width 200))
    …)

?

That would ensure we’re only changing Guile’s notion of the terminal
width and not interfering with other tools we might launch as child
processes.

Thoughts?
