anything starting with :s means :substitute, including :su. But then
:suspend can be abbreviated to :su, that's a conflict.
For each of the commands listed below, the command can be
entered as the abbreviation (those characters in the Synopsis
command word preceding the [), the full command (all characters
shown for the command word, omitting the [ and ]), or any subset
of the characters of the full command down to the abbreviation.
For example, the args command (shown as ar[gs] in the Synopsis)
can be entered as ar, arg or args.
Synopsis: [range] s[ubstitute] [/pattern/repl/[options] [count] [flags]]
Making an exception for :su to mean :suspend instead of :substitute
would be weird.
GALAHAD: No. Look, I can tackle this lot single-handed!
