Handle incomplete diff files properly ()
* Handle incomplete diff files properly

The code for parsing diff hunks has a bug whereby a very long line
in a very long diff would not be completely read leading to an unexpected
character.

This PR ensures that the line is completely cleared

Alternative fix for HTML diff entity split ()
* Alternative fix for HTML diff entity split

This commit both reverts PR  and uses the exiting implementation alredy used for spans to fix the same issue. That PR duplicates most of logic that is already present elsewhere and still was failing for some cases. This should be simpler as it uses the existing logic that already works for <span>s being split apart.

Added both test cases as well.

* Update gitdiff_test.go

* fmt

* entity can have uppercase letter, also add detailed comment per @zeripath

Was missing an optional whitespace check in regex. Also noticed a rare case where diff.Type == Equal would be empty and thus get a newline attached. Fixed that too.

Fix diff skipping lines ()
* Fix diff skipping lines

ParsePatch previously just skipped all lines that start with "+++ " or "--- "
and makes no attempt to see these lines in context.

This PR rewrites ParsePatch to pay attention to context and position
within a patch, ensuring that --- and +++ are only skipped if
appropriate.

This PR also fixes several issues with incomplete files.

Finally fix diff names ()
* Finally fix diff names

 attempted to fix diff by avoiding the git diff line as
it is possible to have an ambiguous line here.

 attempted to fix diff by assuming that names would quoted
if they needed to be and if one was quoted then both would be.

Both of these were wrong.

I have now discovered `--src-prefix` and `--dst-prefix` which
means that we can set this in such a way to force the git diff
to always be unambiguous.

Therefore this PR rollsback most of the changes in  and
uses these options to fix this.

Fix yet another bug with diff file names ()
Following further testing it has become apparent that the diff line
cannot be used to determine filenames for diffs with any sort of predictability
the answer therefore is to use the other lines that are provided with a diff

Improved diff syntax highlighting fix ()
Make previous fix from  more robust since I saw a case where a diff changes only a single character in a chroma class instead of the entire thing. Add another more complicated test to match.

Fix Syntax highlight for token change in added/deleted code ()
* Fix Syntax highlight for token change in added/deleted code

For diffs we first syntax highlight the before and after line then use a 3rd party diff library to find the difference in them and create a substring based on that, which we then highlight a 2nd time to show the specific difference within a line that has changed. In a specific case if the diffrence also changes the chroma class it will split in the middle of the attr and cause broken HTML:

```
<span class="nx">oldtext<span>
<span class="k">var newtext<span>
```

Will then split on

```
<span class="
```

Where the difference starts, and produce something broken like:

```
<span class="<span class="removed-code">nx"oldtext</span></span

```

Fix that by detecting when it happens and putting the HTML back together properly before highlighting the added/deleted code.

Fixes 

* fix lint

* apply fix to all diff sections. Also handle case where insert/remove starts with a closing span

* Add a test for this new code

* remove comment
