Re: housekeeping changes

Hi bill,

Thanks for the patch(es)!  I cherry-picked your patches along with a
series of tweaks and fixes into a temporary refactor-into-functions [0]
branch, squashing and rewording them in form of two commits.  I think my
commit messages are reasonably descriptive, but if you or anyone else
have suggestions for improvements please let me know.

If there are no objections I will do a fast-forward merge of
'refactor-into-functions' into 'master' in a few days and will
delete the temporary branch afterwards.

As a potential next step, would you be interested in looking through
Michał's "bug#41054: Breaking up makeicecat into functions" patch ([1])
from a while ago (my apologies Michał for the delay in getting to this)
and apply a similar finer breakdown of some of the functions?
