[PATCH] argp-help null pointer and dead code fixes

[Colin Watson]

Coverity reported some bugs in man-db which are in fact gnulib bugs. I'd
like to clear these up. This is the most obvious installment, mainly
representing real bugs; I still need to investigate several items which
are essentially false positives and see if it's worth adjusting code to
avoid tripping source code checkers.

        Merge some glibc changes into lib/argp-help.c.

        * lib/argp-help.c: Include <stdint.h> for uint8_t, required by
        changes below.

        2006-05-09  Ulrich Drepper  <address@hidden>

        * lib/argp-help.c (hol_entry_help): Handle STATE==NULL in ARG
        and DGETTEXT calls.
        (hol_help): Likewise.  [Coverity CID 226, 227]

        * lib/argp-help.c (hol_entry_cmp): Don't call canon_doc_option if
        string is NULL.  [Coverity CID 212]

        * lib/argp-help.c (fill_in_uparams): Handle STATE==NULL in
        dgettext calls. [Coverity CID 204]

        * lib/argp-help.c (uparam_names): Reduce size.  Avoid relative
        relocations.  Moved to read-only segment.
        (fill_in_uparams): Update for new layout.

        * lib/argp-help.c (hol_entry_help): Remove some dead code
        [Coverity CID 200].

        2007-03-15  Jakub Jelinek  <address@hidden>

        * lib/argp-help.c (filter_doc): Don't crash if argp is NULL.

Thanks,
