Hi,
I am Attila Molnar, from a small start-up from Hungary
Well the subject pretty well describes the problem...
I tried to override the history file value with:
(package-initialize)
(require 'tramp)
(defvar tramp-histfile-override "~/.tramp_history" "Prevent tramp from
using /dev/null and recreating it as a regular file when history size is
reached.")
With no success. However, I found the problem in the source code and fixed
it:
@@ -3865,7 +3865,7 @@ file exists and nonzero exit status otherwise."
