thanks for having a look at it (no need to apologise for the delay, it's
certainly not an urgent matter).

Captions are now suppressed for longtables without caption definition.
However, I've noticed that the extra linebreak (\\) is still inserted in
longtable environments regardless of the presence of a caption. That
linebreak leads to undesired effects when using longtable without a
caption but with vertical lines.

This should fix it:
