Bug#287876: Bug#276545: Bug#287876: File $HOME/.xsession-errors grows very large

[Steve McIntyre <steve@einval.com>]

Wow, this is an old bug that seemingly got forgotten about!

I've just added locally a change to at least rotate the
.xsession-errors file at startup, to stop me wasting gigabytes of disk
on errors that I don't care about long-term:

diff --git a/X11/Xsession b/X11/Xsession
index 6ad7d6e..8302900 100755
--- a/X11/Xsession
+++ b/X11/Xsession

+if [ -f "$ERRFILE" ] && [ ! -L "$ERRFILE" ]; then
+    mv -f "$ERRFILE" "$ERRFILE".old
+fi

 # attempt to create an error file; abort if we cannot
 if (umask 077 && touch "$ERRFILE") 2> /dev/null && [ -w "$ERRFILE" ] &&
   [ ! -L "$ERRFILE" ]; then
