[TCLCORE] Expect 5.45.4 released

[Nils C. <nil...@lu...>]

Some small progress in the expect development. Here is a small bug fix 
release.

The releases sources are at

	https://sourceforge.net/projects/expect/files/Expect/5.45.4/

 From the changelog:


* exp_inter.c: [https://sourceforge.net/p/expect/patches/22/]
   Fix interact bug - handle reads of 0 length on
   non-blocking channels by explicitly checking if the channel
   is non-blocking. Fix by Jack Bates.

* expect.c: [https://sourceforge.net/p/expect/patches/21/]
   Fix eof bug introduced with previous bug fix - ensure that data
   received just before an eof is processed. Fix by Sergei Golovan.

Cheers,
Nils Carlson
