I'd quite like to have a variant of "typeset -p" that prints array
elements one per line for readability --- this is entirely cosmetic as
the syntax can still be read in.
This uses -P, but if there are suggestions for something less likely to
clash with an option in another shell let me know. I think it would be
too fraught to make this the default for -p as it might be assumed there
is one line per variable.

Need to lower-case that second -P.
I'm ambivalent about this choice of option letter, though. What about
something entirely unlikely to conflict, like -1 (ala "ls -1")? Then
e.g. one could use the idiom "typeset -p1" to make it obvious.
We could also have "typeset -2" to output associative arrays in the old
(k1 v1 k2 v2 ...) format (I suppose "typeset -12" would then print a
newline after each value but not after each key).
I have two requests with respect to the rest of this patch:
(1) Don't print the blank line for arrays with no elements, e.g. NOT
typeset -a cdpath=(
)
Ideally this would just be cdpath=() as before, but I could live with one
line break in the parens.
(2) Indent each element by a couple of spaces.

Handling integer options is difficult as the option parser has special
arrangements. Optional integer arguments are possible, so we could
enforce this as -p1, i.e. your idiom becomes the required syntax. I
think I've got this working; I'll send it later with documentation and
tests.

This message never arrived, but it's been overtaken by events.
The chunk in Src/subst.c is unrelated apart from being required by a
test I've just added. It ensures we don't elide empty nodes from the
list when using key / value pairs. Slight hack here to avoid doing too
much extra processing: it'll keep empty nodes in the old-fashioned part
of mixed array assignments (forbidden for associative arrays). Do you
know, I don't really care? Shocking.
One other minor compatibility note: the existing typeset -p
prints a space between the parentheses of an empty array. This
may have been required for parsing in the past, or may have
simply been to avoid special cases, I don't know. I've removed this
space for typeset -p1.

Hrm, this makes me notice that there's a useful case for typeset -p to
output the [k]=v syntax even for traditional arrays. Consider:
% typeset -a onek=([1024]=something)
% typeset -p 1 onek
We could skip the initial 1023 lines of '' if we used the new syntax.
On the other hand, we'd waste a bunch of bytes on [N]=... if the array
was *not* mostly empty, so most of the time the old syntax is likely
more compact.

Interesting:
torch% typeset -p x
typeset -a x=( )
torch% typeset -p 1 x
typeset -a x=()
(I don't really care either, but somebody is probably going to notice
and file a bug report.)
Aside -- *prior to* this patch:
torch% () { typeset -p 1 } foo
(anon):typeset: no such variable: 1
torch% () { typeset -p @ } foo
torch% () { typeset -p \* } foo
torch% () { typeset -p # } foo
torch% () { typeset -p ARGC } foo
torch% () { typeset -p argv } foo
typeset -g -a argv=( foo )
So individual positional parameters are "no such variable" which nicely
makes this new syntax usable, yet the argv variants are recognized but
not always printable. (Also not clear that the -g is correct for argv,
but I think it's merely extraneous rather than wrong.)

Unfortunately, unlike bash, arrays aren't sparse. So the intervening
elements that haven't been set are identical to any that have been set
explicitly to any empty string. Of course, that could be adopted as a
convention --- on re-input the effect is the same, which is ultimately
the key point.

I only changed it because I was asked.
Cosmetic differences between -p and -p1 are quite explicitly not a bug.
I'll commit it as it stands (with a correction from Daniel).
Hmm, maybe I'll make typeset -p0 the same as -p for consistency.

Sadly, I only asked because I forgot there was a space there in the
first place. I was more concerned with the newlines.
