I propose permitting `soelim` to interpret spaces in a `so` argument as-is,
and supporting `ds`-style leading double-quote removal (allowing file names
that begin with spaces).

Why?

To align with a proposed syntax extension to `so` and other requests in the
formatter.  See bug #65108.

Won't this break compatibility with everybody?

No.  Historically, neither formatters nor _soelim_ programs don't interpret
backslash-escaped spaces as spaces, and in fact _soelim_ programs
traditionally rewrite the first space they encounter in a `so` argument as a
newline (likely putting an undesired partial file name on the output as
formatted text).

See comments 3 and 4 to bug #65108.
