LYNX-DEV lynx patch

[Helen]

Hello lynxers,

here is my very own lynx2-7-2 patch ! It replaces the [LINK], [INLINE] and
[IMAGE] comments (for images without ALT) with filenames of these images.
I find it extremely useful, because now I can see immediately what images
are just decorations (button.gif, line.gif) and what images are important.
(of course, it is guessing, but usually it is very easy to guess).

It uses a variable (verbose_img) which is permanently set to 1,
but it should be easy to put it into configuration file and toggle between
old and new behaviour, if someone will want to implement this option as
the part of the future distribution. (I hope that it will be accepted !)

It must be applied in src directory, and changes the file HTML.c.

Helen
