Scratch that.  It is a bug in bash-completion, after all.  I'm forwarding
this report upstream.  $cur is underquoted, and in your particular case,
happened to be set to '[a-z.]'.  Which means, as written, bash is trying
to perform glob expansion on 'text'[a-z.]'text', and it is bash, not awk,
triggering the warning.

And this strace limitation (bug?) was just a red herring.
