There is a bug in Lynx' handling of at least some HTML tags. If
whitespace precedes the closing '>' of "</script>" then problems occur
(see below for Unix and Lynx version, as well as the HTML source obtained
using -mime_header and the result of using -dump). If the space is
removed, then -dump shows the title and line of text as expected.
This was detected because I have an HTML-generation library that puts a
newline ('\n') before every '>' in order to put the output on multiple
lines without ever inserting unwanted whitespace between tags. The W3C
validator has no problem with this and I have never observed any other
browser to have a problem.
Since I'm reporting things I'd like changed in Lynx, I will also mention
that I'd really like -mime_header to *always* just show what comes back
from the server. If the server response is a 401, then the server headers
are not shown; instead the Lynx error message about access denied is
shown.
Thanks for putting out Lynx. It's still useful....
