I would like to reproduce here a function by David Korn:
==================cut here============================
function readfile # var file
{
nameref var=$1
set -f
IFS=$'\n\n'
var=( $(< $2))
}
==================cut here============================
I presume that [set -f] (disable file name generation) is locally scoped, but
what about the assignment to IFS? It seems to me that IFS is globally scoped
here, hence that assigment would most likey have bad side effects on the caller
code.
