Advice with undo config

[Nick Helm]

Hi there,

I keep bumping into the default undo limits and I'm trying to configure
my Emacs for greater undo capacity. If I add something like this to my
init:

  (setq undo-limit        (* 16 1024 1024))
  (setq undo-strong-limit (* 24 1024 1024))
  (setq undo-outer-limit (* 240 1024 1024))

will there be any side-effects I should be aware of? Are these numbers
reasonable? I've tested this setup with some of the files that normally
give me problems and I can undo until the cows come home without any
obvious issues.

Many thanks!
Nick
