Worse still, its use breaks some rdoc, replacing method names with a curly brace.
Having just one call-seq directive doesn't add anything since this is covered by regular rdoc.
Having multiple might make sense, but these are already documented with examples.

This partly re-reverts 60de0e56 but does not
touch the vendorized code in html-scanner.

Revert "call-seq directive makes rdoc cry and replaces method names with a curly brace; besides it doesn't add anything when you only list one call example since this is obviously documented already"

Reason: Part of this commit touches vendorized stuff, the rest is fine, could you please repatch?

This reverts commit 60de0e56.
