Fwd: Space in dirs break `make install`

[Ole Tange]

I use autoconf for GNU Parallel.

$ autoconf --version
autoconf (GNU Autoconf) 2.69

If I create a user with a homedir: "/home/  space  " and use

  ./configure --prefix "$HOME"

Then "make install" fails:

make[3]: Entering directory '/home/  space  /parallel-20200922/src'
rm /home/  space  /bin/sem || true
rm: cannot remove '/home/': Is a directory
rm: cannot remove 'space': No such file or directory
rm: cannot remove '/bin/sem': No such file or directory
ln -s parallel /home/  space  /bin/sem
ln: target '/bin/sem' is not a directory

The problem is most likely never going to happen on real Unix systems,
but I have seen similar problems on Microsoft Windows where dirs with
spaces are quite common.

I have not determined the root cause, but I think you may have
problems if the dirs contain multiple consecutive spaces.
