PSPP-BUG: Add html CODE tags to manual

[Eliana]

Sorry, the web interface is too hard for me to use.

Add html  CODE tags to html versions of the  manual.   Those are html
tags that tell translation
engines not to translate the text indicated.

Without those tags, translation engines happily translate commands
into the foreign language, totally disregarding their sanctity and
rendering the translation very confusing and possibly erroneous in some cases

Adding these tags is not a  trivial project, but
requires no knowledge of any foreign language, and I believe would
render the online manual a meaningful document for a larger portion of
the international community without requiring  translating separate
manuals for each language.

But it will require proofing of the translated pages to spot any items
that needed code tags which have not been generated - translation
engines definitely also translate   abbreviations and special
characters. and add unexpected punctuation marks inappropriately.
Proofing is easier if someone knows the foreign language, but if you
know the manual contents, you will see things that look wrong even if
you do not know the foreign language.
