My requests are:
- Directory fd support, aka ~{fd}. The patch Roland posted is very
short and limited to a specific functionality and should be quite low
risk - still it provides a ingenious way to have short paths relative
to a directory fd with the same functionality as a shell's cwd.
- ksh93v has a bunch of .sh.match fixes which would be very welcome here
- poll builtin
