Description of problem:
When using code like

   printf "%'d %d"

in a script currently both numbers are printed using thousand separators (given
the numbers are large enough).  This is not correct, the flag should not be sticky.


Version-Release number of selected component (if applicable):
gawk-3.1.5-15.fc7

How reproducible:
always

Steps to Reproduce:
1.store this in a file:

env LC_ALL=en_US.UTF-8 \
./gawk < /dev/null -f /dev/fd/3 3<<'EOF'
END { printf "%'d %d\n", 1000000000000, 1000000000000 }
EOF

2. run using bash or so
3.
  
Actual results:
1,000,000,000,000 1,000,000,000,000


Expected results:
1,000,000,000,000 1000000000000
