External commands that are invoked to generate completions (
receive the word preceding the completion word as an argument,
as described above.
This provides context that is sometimes useful, but may include
information that is considered sensitive or part of a word expansion
that will not appear in the command line after expansion.
That word may be visible in process listings or in audit logs.
This may be a concern to users and completion specification authors
if there is sensitive information on the command line before
expansion, since completion takes place before words are expanded.
If this is an issue, completion authors should use functions as
wrappers around external commands and pass context information to the
external command in a different way.
External completers can infer context from the
