Action UI names can clash with GUI-specific mnemonic syntax
If an action UI name contains a client GUI's mnemonic character, nothing stops the GUI turning it into an unwanted mnemonic.
This is most likely with the Qt client, where the mnemonic character is '&'. An action name like 'Steal&Escape' is not completely implausible.
Fortunately, all (both) the mnemonic systems we currently have to deal with support escaping-by-doubling, which makes it easy to cope with this centrally.
