FPAT/printing fields bug

[Ed Morton]

Looks like there's an FPAT bug in gawk 5.0.1:

$ echo ',b' | gawk -v FPAT='[^,]*' '{print $2}'
b

$ echo ',b' | gawk -v FPAT='[^,]*' '{print $1, $2}'

$

It can be worked around in the same way as a previous bug 
(https://lists.gnu.org/archive/html/bug-gawk/2017-04/msg00000.html):

$ echo ',b' | gawk -v FPAT='[^,]*' '{oFPAT=FPAT; FPAT=""; FPAT=oFPAT; 
print $1, $2}'
 b
$
