Strictly speaking, you are not introducing your own subshell to
prevent the environment from leaking (i.e. you used "{...}" not
"(...)" in the previous step). The reason you can do this is
because the generation of UNICODEWIDTH_H file is the last thing in
the subshell.
I'll reword it to "Since this is done as the last command, ..."
Thanks.
