top: swat a bug with 3.2.8 support for field additions

Browse Source 
This new integer based version of 'fieldscur' deviated
a bit too much from that character based logic when it
comes to ancient 3.2.8 rcfile support. This results in
an inappropriate extra field shown as the last column.

If we're truly dealing with 20 year old 3.2.8 rcfiles,
it's important the 3.3.9 extension (RCF_PLUS_H) not be
concatenated to what was read. That's because a search
for the special SUSE characters will always find a '\'
in the 26th position (after normal 3.2.8 'fieldscur').

[ for symmetry, we'll also avoid RCF_PLUS_J (3.3.17) ]

All other 'old' rcfiles are transformed without error.
