Change <code> blocks on website to use 4 spaces per tab.

[stippi]

The coding style guide explicitely mentions to use 4 spaces per tab, yet the examples are displayed with 8 spaces per tab on the website.

Unfortunately ​several ​sources give the impression that this is impossible; a \t is interpreted as 8 spaces and this cannot be changed.

The workaround would be to reformat the tabs to four spaces, but then of course when copy-pasting it no longer conforms to the style guide.

Assuming that you are still using the Geshi Filter Module version 1.0.8.4, changing line 503 of geshi.php in the module directory from...

    var $tab_width = 8;

to

    var $tab_width = 4;

...will at least in theory change the tab stop size and most likely do the trick.

For the above change to work, you would also have to change the "Code container, wrapping technique" setting in admin/settings/geshifilter to use a <div> wrapper. I don't know if this would have any ramifications or not.

Fixed: With the setting from comment:3 I was able to update it.
