- OpenFromFile builds the new content in a separate PieceTable and
swaps it in only when complete. A reload that ran out of memory used
to leave the buffer empty (filename, journal and dirty state intact),
and the next save truncated the file.
- Editor::ProcessPendingOpens catches exceptions from opening (it runs
in every frontend's loop, outside command dispatch, so bad_alloc on a
huge file ended the editor); the terminal draw is guarded too.
- The hard-link save copy uses a unique mkstemp name, so a leftover
copy no longer blocks every later save; if no copy can be created the
file is still written in place.
- When no temp file can be created in the directory (file writable,
directory not), an existing regular file is written in place instead
of the save failing.
