zsh-2.6-beta18: an incompatibility with ksh in typeset command

[suzuki@xxxxxxxxxxxxxxxxxxxxxxxxx (SUZUKI Hisao)]

     This is a report on the problem which I had noticed in
zsh-2.6-beta16 and had sent you a bug-report on the 9th May.
But it seems that no improvement had done for now.  Maybe my
report had lost somewhere no one knows...  So, I decided to
report it again.  (Excuse me if this is a redundant report.)

     The problem I found is a slight incompatibility between the
Z Shell and the Korn Shell (ksh, hereafter).

     In ksh, the optional numeric argument of `typeset' command,
which is typically used to specify the output arithmetic base,
is placed just after the option(s) of the command:

	$ typeset -i2 a
	$ a=10
	$ echo $a
	2#1010
	$ 

In zsh-2.6-beta18, however, you must put a space between the
option and numeric argument, like this:

	% typeset -i 2 a

This is an annoying difference.

The following is a sample fix; it preserves the backward
compatibility by extending only the erroneous case, though it is
quick-and-dirty...
