everything above is ok, but on closer inspection I found that I had a
leftover libedit.so.2.11 in /usr/lib/i386-linux-gnu. It does not belong to
any package in my sid system, but it is identical to the version shipped in
the wheezy package. I would like to know how this happened to remain in my
system. In any case, you were right, it was not a bug in php5-readline but a
stray library. My best guess is that it was left over from some less then
perfect system update. Of course, ldconfig linked libedit.so.2 to
libedit.so.2.11 instead of libedit.so.2.0.47, since it (wrongly) looks like 
the later version.

This was a nasty one to find. I would suggest that you forward this to the
maintainer of libedit, to investigate whether this might be a common problem
in upgrading from the wheezy version to sid. My laptop is a good guinea pig,
in this respect, since I trace sid rather regularly and hardly ever put any
file where it should not go in the debian file system hierarchy (I am quite
anal bout this).

Thanks for your help and patience, bye
Giacomo
