Hello,
as alioth.debian.or is down, replace at
https://www.gnu.org/software/bash/manual/html_node/A-Programmable-Completion-Example.html
the reference from http://bash-completion.alioth.debian.org/ to
https://salsa.debian.org/debian/bash-completion .

Over in the "here strings and tmpfiles" thread, a distraction came up,
which i'm splitting out into a separate thread. Please don't conflate
the two, i'm just looking for further clarity about process
substitutions and the wait builtin.

then a call with less than 3 parameter, eg. "./shift.sh 1 2" gives ">>1 2<<".
Whilst the man page does not deny this behaviour I do wonder if a feature
request to get ">><<" instead is sufficient here?
