quasilit: move separator defaulting to fmt_cat.

The motivation here is an upcoming change in which
we will support the separator modifier for buffers
and strings. Currently, it does nothing. If we write
`@{a ":"}`, and a is a buffer or string, the separator
is ignored. We don't fix that in this commit, but
we fix the problem that some higher level formatting
functions are defaulting the separator to " " (single
space) and passing it down. We want to control the
defaulting based on the type of the object in one place.

* eval.c (fmt_cat): Do not assume here that sep has been
defaulted; do the defaulting to space here.
(format_field, fmt_flex): Initialize the separator to nil,
not space. If no separator occurs among the modifiers,
it gets passed down as nil through to fmt_cat.
(fmt_simple): Don't default the sep argument to space;
pass it through to do_format_field which will pass it down
to fmt_cat.
