[Debian GNUstep maintainers] Bug#1134346: unar: Some Imploded zips fail to extract

Package: unar
Version: 1.10.7+ds1+really1.10.1-3build1
Severity: normal
X-Debbugs-Cc: ray.chason at proton.me

Some Zips using the Implode method fail to extract, even though unzip extracts
them successfully.

An example can be found at http://cd.textfiles.com/gigabytesw/001a/comm3.zip .

If I build unar from the Github source, this Zip extracts successfully. If I
apply the first patch (CSInputBuffer-bit-string-reading.patch), the element
TERM.EXE fails to unpack. It's hitting the end of file exception in
_CSInputCheckAndFillBitsLE.
