Properly handle Ctrl+C; add '?' and 'man' aliases; don't import symbols
Make Ctrl+C behave like in the shell (abort current line, redisplay)
Add '?' and 'man' as aliases for help
Add qw// on module 'use's to not import any symbols
Do not sort flaglist twice
With this change, 'inspect'ing an element prints its attributes
in a defined order: (requiredness, multivaluedness)
Previously, the order was alphabetical and varying.
