* Simplify exm(1df)Tom Ryder2018-06-211-2/+1
| | | | | I thought shell script stripped \r from the end of variables, but that does not actually seem to be the case. I think it's just newlines.
* Move exm(1df) test into EDITOR selectionTom Ryder2017-05-141-8/+5
| | | | | | Merely checking for vim(1) is a poor test; we specifically need to know if the ex(1) implementation is Vim, so test it while making the EDITOR decision.
* Apply runtime shebanging to POSIX shellTom Ryder2017-04-051-0/+12
