Add missing xhtml end tag.
Generate html5, not xhtml.
Use id-based fragment identifiers.

a name is deprecated.
Move </tr> to right place.
Add missing alt text for img.
Correct splitting of git-ls-tree output

Split limit 5 was off by one, which resulted in incorrect
processing of file paths with spaces embedded in them.
New split limit of 4 gets the required parts, because it
specifies the allowed number of splits, not elements:

mode type hash size name
    1    2    3    4
