justification: when leading whitespace exceeds fill width, wrap anyway

Pico wraps at the last blank character before or on the target column;
if there is no such blank, then it will wrap at the first blank *after*
the target column -- when it can wrap, it will wrap.  Nano should do
the same (and judging from the comments, it intended to do the same),
instead of turning the paragraph into a single unwrapped line.

This fixes https://savannah.gnu.org/bugs/?53986.
