- Buffer::insert_row recorded its text and newline as two swap records
after inserting both. A checkpoint triggered by the first (1 MiB of
edits, or the checkpoint timer) snapshotted the newline already, and
the second added it again on replay: recovery after undoing C-k C-k
silently gained a blank line. It is now one record.
- Visual-line yank placed the cursor relative to its row assuming that
row was inside the selection; after C-k a or Enter it was not, and the
cursor ended past the end of a line or the buffer, where typed text was
recorded for undo at a position it was not inserted at and could not
be undone. The formula uses the nearest selected row, and run_handler
now clamps the cursor to the buffer before and after every command.
- ENABLE_ASAN added -fsanitize=address to CMAKE_C_FLAGS only; the
project is C++, so nothing was instrumented. Add it to
CMAKE_CXX_FLAGS.

After a lost record the journal drops position-based records until a
full checkpoint. That checkpoint was only requested from later edits,
rate-limited to once a second; when the writer handled the failing
record before its edit asked for a checkpoint, the checkpoint failed as
well and consumed the slot, so edits made within the next second were
not recovered and, if the user stopped typing, the journal stayed behind
indefinitely. SwapManager::RetryGapCheckpoints(), called once per frame
from Editor::ProcessPendingOpens, requests it once the interval has
passed. This also made SwapReplay_LostRecord_ResyncsWithCheckpoint flaky
under load; the test now exercises the retry.

- 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.
