Hints
=====

* tiny-regex-c requires + to be escaped in the following regex.

* oed requires an address after the 't' command.
  Specify the current line with '.'

    OLD: /tea/t
    NEW: /tea/t.

* DOS doesn't really do pipes

    OLD: printf ",p\n" | ed TODO.txt

    OLD: r ! ls -l
    NEW: !dir /lfn >tmp.txt
