Files with multiple consecutive spaces cause errors

[Boris Gjenero]

I was trying to use checkinstall to create a package for projectM music visualizer which I compiled. I already made a tar.xz and was doing "sudo checkinstall tar -C / -xJf /d/projectm-linux-x86_64-20211102.tar.xz" and that was failing with a bunch of errors after "Installation successful":

======================== Installation successful ==========================

There is a lot more of this. These files indeed do not exist in the .tar.xz or on disk once it is extracted. I tracked down a bunch of the files, and all the corresponding files which do exist have two consecutive spaces in the file name. Apparently checkinstall turns two consecutive spaces into a single space, and then fails to find the file.

As a simple test, I created a .tar.gz with "/usr/local/Hello World" (with two spaces between Hello and World) and "/usr/local/Hello World" (with a single space). Creating a package via "sudo checkinstall tar -C / -xzf /d/break_checkinstall_spaces.tar.gz", only the file with a single space gets included, though I don't see the "Cannot stat: No such file or directory" error.

Using --fstrans=0 or --fstrans=no doesn't help.
