src/bin/ksh/NOTES says:
- field splitting (IFS): ksh88/ksh93 strip leading non-white space
IFS chars, pdksh (and POSIX, I think) leave them intact. e.g.
$ IFS="$IFS:"; read x; echo "<$x>"
::
prints "<>" in at&t ksh, "<::>" in pdksh.
but i cant see anything to justify the double-counting of IFS.
> seems to be the way set is used.
printf %s\\n x$msg1
shows set is not to blame (the blank line indicates an empty field).
sorry i cant say anything very useful about it.
