[R-SIG-Mac] Can't save history using savehistory()

[Ken.Williams at thomsonreuters.com]

Hi Rob,

I do see commands appended to the bottom of the history pane during my
session, but when I quit & re-launch they're gone again.

Perhaps they're being saved to a different location than they're being
read from?
