Hi Bart :))
Definitely, if you ever come to Spain, I owe you a good dinner ;))

Yes, I've read them, although I've not tried to understand all of
them, since I've not read all the -x completion yet.

Yes, this one was the first I got, because the examples are more
or less clear and my own experiments led me to this conclussion.

Yes, this is another clear use I understood. The '-' doesn't

And the one I really didn't understand. I mean, the -x args
(specially p, P and r comes to mind) delimit a portion of the command
line that must be completed specially (well, more or less), and the
-l says if it must be completed as a command itself or as an
specified command. No problem with it. What confused me is the
documentation about -l:
This option restricts the range of command line words that
are considered to be arguments. [...] . Completion is then performed
as if these had been given as arguments to the CMD supplied with the
IMHO, this option doesn't really restricts what in the command
line is an argument :??? It is more like an alias. The only way of
really restricting ranges is using -x. And the second paragraph...
Well, I must admit that my completion knowledge is worse than my
english, but I don't get the meaning of that... The completion is
performed in two ways: command-like or using 'CMD' completion :??
> Note that order is important with "-x"
Yes, I've read that in the manual.

I've used it with -u, for example, for completing user names,
just like the example in the manual.
Well, thanks a lot for your explanation. The fact is that I got
more or less well how -l works, but the documentation is bizarre...
