[Nano-devel] [PATCH] justification: when leading whitespace exceeds fill width, wrap anyway

[Benno Schulenberg]

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, instead of leaving the line entirely unwrapped.

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