In <http://grass.osgeo.org/grass71/manuals/g.parser.html>, "Notes":
--%<---
...individual comma separated identities for an option named "input"
can be parsed with the following Bash shell code:
IFS=,
for opt in $GIS_OPT_INPUT ; do
... "$opt"
done
--->%--
Doesn't this require to set the IFS back to what it was? Maybe note it
too?
I've been trapped in this (as usual, not being careful):
