- Save's in-place fallbacks (no temp file; no hard-link copy) now apply
only when the directory refuses a new name (EACCES, EPERM,
ENAMETOOLONG). On ENOSPC, EDQUOT or EIO the in-place write truncated
the file and then failed, leaving it corrupt; now the save fails and
the file is untouched (checked on a full tmpfs).
- replace_rows_text/replace_buffer_text delete and insert only the span
between the old and new text's common prefix and suffix (kept on
UTF-8 boundaries). Replace-all recorded the whole buffer twice in the
undo tree per run.
- Regex search skips long lines only while typing (limit lowered to
2,000 bytes, as for renderer highlighting; '.*q' on a 20 KB line took
12 s), reports how many were skipped, and next/previous match search
every line. Previously matches on long lines could not be found.
