I not necessarily agree; I think that symbolic links are sufficnetly
rare that a bit more time spent to make the view better for end user
(link only if target exists) is worth it. But...

Here follows the implementation of this idea: first to read link
target and show it in "tree" view _without_ hyperlink, then
introduction of generic "object" view which does the verification and
redirect to correct view accorting to the type of object, and last
show link target hyperlinked in "tree" view using "object" view/action
link.

While at it implement the same "lazy" solution in commitsha1 commitag
in format_log_line_html subroutine.
