Indeed, but I find "sudo bash; cd /var/www/cgi-bin; vim gitweb.cgi; etc..."
just as easy! :-D

However, ... point taken.

Heh, I only described the above apache config problems (in the spirit of
full disclosure) so that you would not be surprised by certain files not
being in their usual location ... It wasn't a sneeky attempt to get some
apache support! Having said that, my apache version is:

    Apache/2.2.3 (Ubuntu) mod_perl/2.0.2 Perl/v5.8.8 configured

No, it's running as www-data (well, the initial apache is run as root, but
all worker processes are run as www-data - only the worker processes actually
handle requests, I think).

I remember having tried that as well - without success.

I don't have a JavaScript Console. (I suppose that is an add-on? Hmm, I don't
have internet access from Linux... ).

Thanks. [BTW, if it wasn't clear before, you cannot grab the pop-up and move
it out of the way...]

Yep, I suspected as much. Not a Problem.

Yes, this happens whether the re checkbox is set or *not*.

Indeed, this is the regexp I had intended. (I started with a glob pattern,
noticed the re checkbox, checked it, then went back to edit the search
text, but forgot the initial '*' quantifier)

Thanks.
