Andrea, I have figured out what happens. The working patch is in the
attachment. Copy it into the base directory ('manual') and execute:

zcat Shortcuts.diff.gz | patch -p1

In simple words:

1) There must be no white space inside longtable's (or tabular's) format
specification: instead of
   \begin{longtable}[h] { | p{7cm} | p{6.5cm} | }
   \begin{longtable}[h] {|p{7cm}|p{6.5cm}|}
OK, pdflatex tolerates them, but latex2html introduces extra columns
thinking each such whitespace were one more column (although possibly empty).

2) latex2html does not know the command \endhead and treats it as an
additional table row, this leads to an extra row inserted in the HTML
version of the table. To remove it, you can place \endhead in the
latex2html's pseudo-environment:

3) latex2html does not know the command \bottomrule and treats it as an
additional table row, this leads to an extra row added at the very end of
the HTML version of the table. Unfortunately, the %begin{latexonly}
pseudo-environment does not help as pdflatex throws an error. However, it is
possible to replace \bottomrule with \hline, this does not influence the
pdflatex output, and latex2html's extra row gets out.

Perhaps fixing widths of columns is unnecessary, the reason for the problem
reported was in the extra white space and not in the width expressions.
