Alas, the former fix breaks with path specifications.

The path searching mechanism of pdflatex (when -output-directory is used)
is willing to consider current directory for path like "../../a/b/file"
but is unwilling to consider current directory when only "file" is provided.
Weird.

Alexander, would you mind testing for me 2nd version of the patch?
You need to unwind the last patch ("-R" for patch or just delete the
simple change manually) and then apply the current one.

3 scenarios to be tested:
1. a5toa4 local_file.pdf
2. a5toa4 some_relative_path/file.pdf
3. a5toa4 /absolute_path/file.odf

Works here with TL 2020, but I worry what other changes on searching
mechanisms of -output-directory awaits in the future TLs.
