Revert r53667 "Enabled use of the greater-than sign (">") in page titles. There is actually no reason for this character to be restricted because it does not interfere with wiki syntax or HTML tags. This will have immediate applications for articles such as "M>Tram", ">play", "The Videos 86>98", "Tour 00 >> 01 Macabre", and "I>Télé", as well as redirects for "Inequality" and "Bitwise operation"."
Possibility of spitting raw >s into output unnerves me greatly, and could indeed be a problem depending on just where your text gets spat and what's around it. More generally allowing one half of a pair makes little sense and would simply confuse the issue.
