The "tex\\" is obsolete because GNUmed now already knows the
target language (courtesy of the template) and thusly knows
how to process data.

In case you retained "tex\\" from earlier use GNumed would
include that as part of the text box prompt message, eg
"tex\\Inside address...".

That depends on what you enter. If you enter valid LaTeX code
(such as the above) you need to check

        [x] Do not reformat text

If you enter plain text (potentially invalid LaTeX code) you
need to keep this box unchecked.

I have now enhanced GNUmed to replace EOLs being passed into
a LaTeX form template to get turned into the proper LaTeX
representation "\\" + "\n".

Like that: $<tex_escape::some non-LaTeX-formatted text::max length>$
