Do you actually need to define these "no readline" function versions? I'm
asking because the completer callbacks are transitively invoked from
vshReadlineCompletion (and friends) which is only called from the cmdComplete
which both your and Michal's patch handles. So, are you experiencing any
problems on any platforms without these hunks? (I compiles fine with just the
first and last hunk applied, obviously no readline support)
Anyhow, I went ahead and reviewed Michal's patches, so unless you really need
the hunks I mentioned in the previous paragraph, let's go with Michal's instead.
