For the original problem as spotted in qemu builds Heinrich (thanks
again!) came up with:
From:
len2=$$(($${#list}/2));
if [ $$len2 -gt 36 ]; then \
while expr substr "$$list" $$len2 1 != " " >/dev/null; do
len2=$$(($$len2+1)); done; \
list="$$(expr substr "$$list" 1 $$(($$len2-1)))\$${Newline} $$(expr substr
"$$list" $$(($$len2+1)) $$len2)"; \
fi;
To:
echo "$list" | fold -s -w 36 >> debian/qemu.subst
That is more the tool that is meant to do that and has the added benefit
of working with the rust coreutils already. I tested it with the lists
we get on armhf (short) and others (longer and broken up) - AFAICS it
works. @Heinich - I think it makes sense to submit that to Debian, do
you want to or should I?
