The problem definitely occurs when calling R CMD build from a dir whose
file path contains white space. Now in R CMD build we have
$ grep filepath build.in
my $filepath = &file_path($startdir, $filename);
R_system("zip -r9X $filepath.zip $pkgs $topLevelFiles");
R_system("$tar chf $filepath $pkgs $topLevelFiles");
R_system("gzip -9f $filepath");
my $filepath = &file_path($startdir, $filename);
my $origfilepath = $filepath;
$filepath =~ s+^([A-Za-x]):+/cygdrive/\1+;
R_system("$tar chf $filepath $pkgname");
R_system("$tar xhf $filepath");
R_system("$tar chf $filepath $pkgname");
R_system("gzip -9f $origfilepath");
so in fact in none of the calls to R_system() with $filepath do we
currently perform any kind of quoting or shell escaping.
A simple improvement would be quoting all filepaths in R_system() calls
via \"...\" or '...'. Unless someone has a better idea or wants to put
in more effort ...
