Fix regular expressions not being case-insensitive

Browse source 
The "parser marker" placeholders are case-sensitive, e.g. for a tag
that's written like <rEf> the placeholder will also say …-rEf-…. This
was really just a mistake.

The error is as old as this code is. Added in commit 75004e33 in
2009.

Note we shouldn't use /i at the end because the marker itself should
not be case-insensitive. Only the tag name.

Instead of adding more (slow) test cases I update two that are
exactly about this part of Cite (nested tags) anyway.
