In regards to worries about "unset FOO" not working if FOO is not set:
${FOO+unset FOO}
Is this crazy or clever? It works in Solaris sh. (I know, in most cases,
it's sufficient to just empty the variable, but sometimes it'd be nice to
be able to distinguish between empty and unset.)

Hi,
If you want to contribute shell script functions to gnulib, we would need some
kind of "linker" for shell scripts: A tool which combines a set of shell
script fragments, each defining a number of functions, and a "main" script,
into a complete, runnable shell script. Does someone already have

ECHO_T? New on me.
I could probably do

This came from a pair of sources; my work on portable shell, and the discovery
that glibc's tzselect "requires ksh".
Originally, I thought "there's no way you could implement select in a shell
which doesn't have it, because it's a control structure". And indeed, you
can't.
But you can implement
Hello Bruno,

accepted by people here, I will improve its implementation.
