gitweb: highlight: replace tabs with spaces

Consider the following code fragment:

* test

vim ":set list" mode shows that the first character on each line is a

^I * test$
^I */$

By default, the "highlight" program will retain the tabs in the HTML

$ highlight --fragment --syntax c test.c
<span class="hl com">/*</span>
<span class="hl com"> * test</span>
<span class="hl com"> */</span>

vim list mode:

^I<span class="hl com">/*</span>$
<span class="hl com">^I * test</span>$
<span class="hl com">^I */</span>$

In gitweb, this winds up looking something like:

1 /*
2 * test
3 */

I tried both Firefox and Opera and saw the same behavior.

The desired output is:

1 /*
2 * test
3 */

This can be accomplished by specifying "--replace-tabs=8" on the
highlight command line.
