[PATCH 0/3] Some Coverity fixes from GRUB

[Darren Kenny]

During the recent GRUB releases, I took a look at some Coverity issues that
were found in the gnulib sources that GRUB is using as part of its build.

A couple of these issues still exist in the current gnulib master branch
so I've put the fixes for these together to in this patchset.

I did a build using the command:

    ./gnulib-tool \
        --with-tests \
        --dir=/tmp/gnulib-test \
        --test argp base64 error fnmatch getdelim \
               getline gettext-h gitlog-to-changelog \
               mbswidth progname realloc-gnu \
               regex save-cwd

which is fairly close to the list of modules that GRUB is using and there
were not test failures.

Thanks,

Darren.
