It does not appear as a listed construct in
https://pubs.opengroup.org/onlinepubs/9799919799/utilities/V3_chap02.html#t=
ag_19_06_02
which is the official reference, so I'm not going to use it.
In any case, adding a backslash before very newline is the exact kind
of cursed half-baked quoting that causes as many problems as it solves.
(what if there's already a backslash before the newline? etc.)
If the problem is caused by IFS, then it should be solved by IFS.
Setting it back to the previous value should be all the fix that's
needed, shouldn't it?
I’m not sure I get why you changed its value in the first place. If I’m not
mistaken, its default value is " \t\n", expanding "$*" uses the first character
of IFS for separating values. So this should be good for your use case, unless
I’ve missed something, which is very possible. :)
