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
tab:
^I/*$
^I * test$
^I */$
By default, the "highlight" program will retain the tabs in the HTML
output:
$ 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.
