- `set -o pipefail` is not portable as dash doesn't know about it, and - `set -e` is not very useful if you have a die() function, and [has some problems too](http://mywiki.wooledge.org/BashFAQ/105).
Otherwise you can get the following error: ``` $ ./portable-screencap --dfdf ./portable-screencap: 20: ./portable-screencap: die: not found ```

Here are some changes to portable-screencap.
It looks like many of those fixes could be aplied to ipfs-screencap too, but that will be for another PR.
