This adds an _arguments based completion function for read. I don't think
we have too many builtins left where conversion to use _arguments would
still be useful. Any requests?
I thought about modifying _vars to insert the '[' for arrays and
associations but _parameters would first need to be given an option to
make it only complete specific types of parameter. Would anyone object
to my adding this? I was thinking of a -g option (analogous to the -g
option of _files) where the pattern specified would be augmented with
~*local* and used to match the values in the $parameters association.
I mentioned this vaguely before in 11284 and Sven had some good ideas
in his reply (11293). The focus there is more towards having the
patterns configurable via a style similar to the file-patterns tag but
my suggested option would I think be a useful first step.
