I’ve just pushed three commits that
1. Add “o555” as an octal shorthand
2. Perform a simple check that integer modes are valid*
3. Make the ls-style regex stricter

Thanks. It helps that this list is fairly friendly to begin with :)

All the best,
Timothy

* For example, “:tangle-mode 755” will now produce the warning:
  “1363 is not a valid file mode octal. Did you give the decimal value 755 by
  mistake?”. Maybe it would be worth adding “if so try o755” or similar?
