:-) In case you have a LaTeX document, it's rather easy to circumvent
the problem by moving the float or table, or slightly adjust some
parameters to avoid the effect.  However, for generated files coming
from pandoc, this possibility is not given – except if the created
intermediate LaTeX document gets manually modified, but this
completely defeats the very purpose of pandoc.

I've read the LPPL3.  However – and this is probably a bug itself –,
the following text can be found at the very beginning of
longtable.sty:

  %% This file may only be distributed together with a copy of the
  %% LaTeX `Tools Bundle'. You may however distribute the LaTeX `Tools
  %% Bundle' without such generated files.
  %% 
  %% The list of all files belonging to the LaTeX `Tools Bundle' is
  %% given in the file `manifest.txt'.

It's quite clear that the `Tools Bundle' isn't a single file...

It is my plan to add a remark, of course.  To avoid any issues, I
could even rename the file itself to, say, `longtable-fixed.sty',
since I have control over pandoc's LaTeX template.

This would be great!  However, a general fix to longtable.sty is a
*much* better solution in the long run :-)
