Before the list gets too picky to answer questions from those of us who
can't seem to navigate the cygwin site, would someone kindly tell me
where I can find the actual cygwin sources of all the bits that
accompany cygwin1.dll in full.exe.

As Chris is in denial mode wrt ash I'll need to have a go at fixing the
missing character problem in the pattern match. (He is right in saying
that it isn't something that the Bourne shell can do anyway so what/who
decides the correct behaviour is possibly a moot point).

Denial mode?  You want ash to handle the same substitutions as bash.  It
isn't going to happen.

As to who decides the correct behavior, it's not a moot point.  It's me.

If someone can point me to some documentation that proves that ash is not
working like a standard UNIX /bin/sh, then I'll be happy to change my mind.

That's a good point. Where can we find documentation about ash? 
From experimenting with it, it looks like ash can do more than (some) sh. For example the %% construct can be used to test if an argument is a switch. However this feature doesn't work reliably:

~: sh try_ash yyy
Test 1 yyy
is not a switch
Test 2 yyy
is not a switch

~: sh try_ash -yyy
Test 1 -yyy
is a switch
Test 2 -yyy
is not a switch

Using sh on a SUN yields:
1-chablis$ sh try_ash yyy
try_ash: bad substitution

This is exactly the opposite of the point I was making.  I don't care AT
ALL about the %% construct unless someone can show me somewhere where
this is documented for a UNIX /bin/sh.  So, demonstrating how it
works with ash currently is fruitless.  We already know that it isn't
working right.

As far as i can tell now, the %% behavior should be expunged from ash
I will try to do that for the next release.

That's a good point. Where can we find documentation about ash?

There were a few versions of /bin/sh (well, one per vendor at least).

Which /bin/sh will you model your efforts on?

I'm not aware of much disparity between /bin/sh's.  The one exception
that I am aware of is on Ultrix which we hardly need to consider.

It was perhaps unkind to tweak Chris' tail, but I would expect that if
ash
accepts an expression for evaluation, (one which the Bourne /bin/sh
won't entertain), and the expression requests the longest possible
string up to but not including the nominated terminating character, I
don't expect to be delivered one character short. If the expression in
ash has a completely different meaning than it does in bash then Chris
is right. However he hasn't stated that the rule for interpreting the
expression is different in ash and bash.

So either the expression evaluation is incorrect or
the syntax of the expressions is identical and their semantics are
different.
Which is it?

The expression evaluation is is incorrect in that it is actually parsed
by ash rather resulting in a "bad substitution" error.  In the next
net release this problem will be rectified.

Here you can find all the information you need to fetch/build the 
installer from source:

http://sources.redhat.com/cygwin-apps/setup.html

You may find it interesting to check the cygwin-apps mailing list 
archives:

http://www.cygwin.com/ml/cygwin-apps/

The setup developers exchange ideas and coordinate their work on that 
list.

Don't forget to contribute your changes (if any) back to the comunity :)
