The POSIX standard only requires the read builtin to handle -r:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html
However, Bash introduced the option -d <DELIM> to override IFS for
just one invocation, and it is quite useful.
It is also super easy to implement in BusyBox' ash, so let's do that.
The motivation: This option is used by Git's test suite.

This patch fixes this by initialising OPTIND after importing the
environment.

[VAR] Use setvareq to set OPTIND initially
There is no need to setvarint to set the initial value of OPTIND
of one. This patch switchs to setvareq which also lets us avoid
an unnecessary memory allocation.

This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).
