Maximum wiki code length for customized signatures.

Warning:

This does not consider the length of the substituted templates used in the signature, so although {{subst:<Very long template name>}} will be rejected if the template name has more than $wgMaxSigChars (-10) characters, {{subst:Main page}} will work even if the main page is a lot longer than $wgMaxSigChars (bug 10715).
