filefct bug fix

doc/CHANGELOG.md

@@ -53,6 +53,16 @@ Versions follow `MAJOR.MINOR.PATCH-REVISION_STAGE_N` (e.g. `3.99.1-4_rc_1`).
   `\_`-style escapes are protected from emphasis/link parsing; `NO_COLOR` is
   honoured in tables and headings; fewer subprocesses when rendering tables;
   newlines in arguments no longer break option parsing.
+- `filefct.sh`: `findzero` with `fd` listed (and `--delete` removed) one-byte
+  files; `findzero --delete` could remove symlinks to empty files; `rmspc`
+  overwrote existing files, passed a wrong replacement character to
+  subdirectories with `-r -c X`, followed symlinked directories and mishandled
+  `&` as replacement; `expandlist` split names containing spaces, ignored `\n` in
+  its separator and reset the caller's `nullglob`; `file_stats` histogram was
+  unordered, `--min` was exclusive and invalid sizes silently gave no result;
+  `findbig` accepted an invalid configured limit; names starting with `-` are
+  handled; `finddead` and `findzero` no longer return 1 when the last entry
+  was skipped.
 - `compress.sh`: option flags and loop variables no longer leak into the
   interactive shell.
