[PATCH, doc]: Fix "POD document had syntax errors at /usr/bin/pod2man line 69." error

[Uros Bizjak]

Hello!

Attached patch fixes following errors in .pod document sources:

gfdl.pod around line 53: Expected text after =item, not a number
gfdl.pod around line 147: Expected text after =item, not a number
gfdl.pod around line 165: Expected text after =item, not a number
gfdl.pod around line 205: Expected text after =item, not a number
gfdl.pod around line 357: Expected text after =item, not a number
gfdl.pod around line 384: Expected text after =item, not a number
gfdl.pod around line 400: Expected text after =item, not a number
gfdl.pod around line 422: Expected text after =item, not a number
gfdl.pod around line 445: Expected text after =item, not a number
gfdl.pod around line 475: Expected text after =item, not a number
gfdl.pod around line 499: Expected text after =item, not a number
POD document had syntax errors at /usr/bin/pod2man line 69.
gmake[3]: [doc/gfdl.7] Error 1 (ignored)

As suggested in the fix for a similar problem [1], the solution is to
put "Z<>" in the "=item" argument string.

    * texi2pod.pl: Force .pod file to not be a numbered list.

The fix was tested by bootstrapping on Fedora20 x86_64-pc-linux-gnu,
and also comparing previous .man and .html files with new ones. They
were bit-exact.

OK for mainline and 4.9?
