        It's basically Laura's patch, which Klaus added to the devel
code as is, but which I cast into the "Lynx programming style" (as
defined by me during the past 3 years, and not recorded anywhere,
such that others can only infer it from the existing code 8-), plus
some safety checks, and additions of comments to help explain what
that PRE stuff and concerns about wrapping are all about (which
was too esoteric from just looking at the code, such that Laura's
test HTML file didn't have what's necessary to test it 8-).

        Yes, the submit and reset button values are now being
written directly into the HText structure, instead of just the
underscore placeholders for them, so you will get hits for WHEREIS
searches if their values contain your query term.  The HText structure
still does, and must, have just the underscore placeholders for other
FORM fields, so you won't get hits for those even though their current
values are displayed (by overwriting the placeholders with as much as
fits in the editing window for them, and which the placeholders ensure
will be there, available for overwriting when that section of the
HText strucure is converted to screen output).  The submit and reset
button values also get overwritten in conjunction with converting the
HText structure to screen output and bolding or reversing them as a
link or the current link, respectively, but the actual characters in
them don't change now.
