begin using unsigned arithmetics internally as much as possible
...
(i.e. where signedness doesn’t matter, given -fwrapv) and note
where there’s work to do; note future improvements and additions;
optimise a little
mostly untested

AT&T SVR4 broke 'cc -c -o foo.o foo.c' totally
switch to an alternative method of finding out the prototypes
provided in IRC by dalias (thanks); RT says this fixes his
issues on SVR4 – let’s just ignore the ominous message from
cid 1004713D70A5362BACF about needing to be a compile-time
check unless something else pops up, I can’t think of something
that isn’t already covered

use a different approach to the $"…" problem:
...
take the states that may open a string, only permit them by virtue of
moving the code out of Subst: to handle $+" and $+' at all; then add
S[Q]BRACE to that
side benefits:
• clearer, cleaner code flow
• smaller code
• better “business logic” ☺
• defuses one heavy use of duff’s device a bit
