The Configure script of pari doesn't support Tab key completion of the supported options.

Hi here,

I noticed the following strange thing: The Configure script of pari
doesn't support Tab key completion of the supported options, as shown
below:

werner@X10DAi:~/Public/repo/pari.math.u-bordeaux.fr/git/pari.git$
./Configure --<Tab><Tab>

The above command doesn't give any hints on the supported options by
the Configure script.

On the other hand, the configure script of gp2c supports Tab key
completion, as shown below:

werner@X10DAi:~/Public/repo/pari.math.u-bordeaux.fr/git/gp2c.git$
./configure --<Tab><Tab>
--bindir=                      --localedir=
--cache-file=                  --localstatedir=
--config-cache                 --mandir=
--datadir=                     --no-create
--datarootdir=                 --oldincludedir=
--disable-dependency-tracking  --pdfdir=
--disable-FEATURE              --prefix=
--disable-option-checking      --program-prefix=
--disable-silent-rules         --program-suffix=
--docdir=                      --program-transform-name=
--dvidir=                      --psdir=
--enable-dependency-tracking   --quiet
--enable-FEATURE               --runstatedir=
--enable-maintainer-mode       --sbindir=
--enable-silent-rules          --sharedstatedir=
--exec-prefix=                 --srcdir=
--help                         --sysconfdir=
--help=                        --version
--htmldir=                     --without-PACKAGE
--includedir=                  --with-PACKAGE
--infodir=                     --with-paricfg=
--libdir=                      --with-paricfg-dbg=

Any tips for this strange behavior?

Regards,
Zhao
