73# Hi,
74#
75# I have observed the following changed behavior between gawk-3.8.1 and
76# gakw-4.0.0. While in the former
77#
78# echo -ne ' aaa' | gawk '{for (c = 1; c <= NF; c++) {gsub("foo", "bar", $c); print}}'
79#
80# prints:
81#
82#  aaa
83#
84# the gawk-4.0.0 does not preserve the leading spaces and prints:
85#
86# aaa
87#
88# Best regards,
89# --
90#   Kacper
