Change ``set device'' so that it parses its arguments as one
device per argument rather than the old way of concatenating everything then splitting the result at commas and whitespace. Old syntax of ``set device /dev/cuaa0, /dev/cuaa1'' may no longer contain the comma, but syntax such as ``set device "!ssh host ppp -direct label"'' is now possible.

@ -80,3 +80,6 @@ o Random dial timeouts are now between 1 and 30 seconds inclusive rather
|
||||
than between 0 and 29.
|
||||
o Ppp now accepts M$CHAP (as well as normal CHAP) by default. If this
|
||||
is not required, you must ``deny chap05 chap80''.
|
||||
o The ``set device'' command now expects each device to be specified as an
|
||||
argument rather than concatentating all arguments and splitting based
|
||||
on commas and spaces.
