The patches LGTM, but there is a minor issues WRT the tag area. Since
this patch contains a

From: Paolo Lungaroni <paolo.lungaroni@xxxxxxxxxxx>

tag, Paolo's sob should come first.

According to the the newly created shell script comments, it looks like
the patch as been co developed by both Paolo abd Andrea.

In that case the correct tag sequence would be:

SoB Paolo
Co-devel Andrea
SoB Andrea

Since the above is relevant for correct patch authorship attribution I
suggest to address that in a new revision.

BTW, I a really appreciate the descriptive-but-not-too-verbose commit
