Colons in particular will be a problem.

The reason is that etcupdate's "-s" option takes several different
types of arguments, and one of the possible types is a colon-separated
list of files (e.g. {etcupdate -s etc.tgz:xetc.tgz}).  The main reason
that etcupdate does this is because postinstall does the same.  The
main reason that postinstall accepts a colon-separated list of files
is to make it easy for etcupdate to invoke postinstall.  For example,
if you run {etcupdate -s etc.tgz -s xetc.tgz} then etcupdate will run
{postinstall -s etc.tgz:xetc.tgz [other options]}.

The obvious way of fixing this would be to remove the ability to use
colon-separated lists of file names, and to let multiple "-s" options to
etcupdate be passed through as multiple "s" options to etcupdate.  The
quoting issues are a bit of a problem, but I can deal with them if there
is no objection to removing this syntax.
