user name in /etc/passwd GCOS field

[Bill Wisner]

The most commonly used format used in the GCOS field is Full Name,junk,junk.
This is mainly used on BSD systems but I know of some SysV sites that have
picked up the habit.

The standard format on System V seems to be, thanks to the vanilla passwd
file packaged with it, junk-Full Name(junk). Revolting, isn't it?

It's probably best to check for both. And, of course, allow for a field
containing nothing but Full Name.
