output file with the temporary one by appending ".X" to generate
the temporary fuile's name. If the output file already has an
extension, replace it with ".X".

not $DESTDIR, to find applyfix. Use sprintf instead of snprintf;
reallocate the command buffer while copying the command-line
argument. Redirect the output directly to the temporary file,
instead of going through another temporary file.

directory. When cleaning up the DONE files, look for them
case-insensitively. Don't try to remove symlinks if they aren't
there.

warnings.

return stdout.
