# Status: R
# 
# Hi,
# 
# I have observed the following changed behavior between gawk-3.8.1 and
# gakw-4.0.0. While in the former 
# 
# echo -ne ' aaa' | gawk '{for (c = 1; c <= NF; c++) {gsub("foo", "bar", $c); print}}'
# 
# prints:
# 
#  aaa
# 
# the gawk-4.0.0 does not preserve the leading spaces and prints:
# 
# aaa
# 
# Best regards,
# -- 
#   Kacper
# 
{for (c = 1; c <= NF; c++) {gsub("foo", "bar", $c); print}}
