(“New variable”, not “new shared library”, because technically ‘libbar’
is a variable in foo.scm.  :-))  But yes, as noted there, it should
typically be one patch per addition.

There’s no written guideline for that, but you can check what other
files do.  Essentially, if this can fit in two 80-column lines rather
than 5 lines, just choose the former.

OK, perfect.

I don’t know those pieces of software, but a good start for the
description is typically their Web page or their ‘README’ file.

Thanks in advance!
