a564153d5c Add a description of the restrictions that red(1) imposes to users, 
and a warning that this "restricted mode" can be bypassed easily by
using symlinks, so that users don't depend too much on it.

8e683e45ef Don't try to decode old-style options if the argv[1] begins with `-' and the 
second character represents some option taking an argument. This fixes
problem when ps(1) is invoked for examply as follows:

$ ps -Ufoobar1234

the above example results in option string being interpreted as
-U foobarp1234 - note extra `p'.

50fc04895e Bogusness may have happened using a variable assignment here before, but 
proper parens mean that fd is always set by open(2) [in any part of C],
and so we can accurately check for it returning -1, without feeling like
we need to initialise fd to -1 in its declaration.

In other words, fix a stylistic/bogus nit.

ef26e821fb Allow whitespace to act as a delimiter in the keywords list given to the -o, 
again, but also allow it in the user-specified header, too.  This is far more
backwards compatible and SUSv3-happy than allowing only comma to seperate the
keywords list.

3afc0fe273 As per behaviour on SVR4 systems, to allow any desirable type of header in the

Process
