autoload path completion with expansions

autoload path completion with expansions

[Bart Schaefer]

Starting from zsh -f + compinit + zstyle '*' format %d (so, no completer style)

% autoload $PWD/<TAB>
`vars' or `shell function'

This surprised me, because

% ls $PWD/<TAB>
file
(list of files in the current directory)

Turns out this is because _typeset (which handles autoload) only calls
_files when the word on the command line already begins with "/" or
"~".

I debated also adding \` to the pattern.  Thoughts?

Turns out this doesn't do the right thing when $PREFIX contains a
valid relative directory name (such as "." or ".." among other
things).

Slightly different patch against the original source.
