As bawolff pointed on in bug 26149 comment 1, bugzilla comments should be as much simple-text as possible.

Linking words is find as an enhancement, but it should not remove the brackets in the process since there are (or will be) bugs in the linker and sometimes a link is not intended.

The following text would be better if the [[ were preserved.

"Lorem [[ipsum]] ([[Dolor (sit)|amet]] - [[consectetuer (adipiscing)|]]) [[eli]]t."

Severity: enhancement
