Is it this that is surprising you:

  parallel echo A{}B C{//}D E{1}F G{1//}H ::: dir2/file.ext ::: dir1/v2

giving the output:

  Adir2/file.ext dir1/v2B Cdir2 dir1D Edir2/file.extF Gdir2H

Here there is a space after Cdir2 because there is a space after
Adir2/file.ext. {//} will rarely make sense if you have multiple input
sources. {1//} will, however.

If it was the above, then you could have given me this simple example
and saved time:

  parallel echo c{//}d ::: DIR/FILE.EXT ::: V2

And asked: "I get 'cDIR .d', I had expected 'cDIRd'. Why do I get the
additional space and .?"

This example would have been much easier for me to see through.
