I would argue it is better without the $~; I can replace the ~ with
$PWD on the commandline, but I can't rename the file to not have
brackets without actually renaming it.

I came up with a reproducible test case for the other issue:
% mkdir '[test] a name with spaces'
% touch '[test] a name with spaces'/{'a file with spaces','another
file with spaces',a file with a unique name','afilewithoutspaces'}
% zip -r test.zip '[test] a name with spaces'
% unzip test.zip <tab> # -> gives "\[test\]\ a\ name\ with\ spaces "
with the space after
% unzip test.zip \[test\]\ a\ name\ with\ spaces<tab> # -> just adds
the space back
% unzip test.zip \[test\]\ a\ name\ with\ spaces/<tab>
# -> \[test\]\ a\ name\ with\ spaces/afilewithoutspaces
% unzip test.zip \[test\]\ a\ name\ with\ spaces/a<tab>
# same
% unzip test.zip \[test\]\ a\ name\ with\ spaces/an<tab>
# -> "\[test\]\ a\ name\ with\ spaces/another\ file\ with\ spaces "
# (as a unique match)
% unzip test.zip \[test\]\ a\ name\ with\ spaces/a\ file<tab><tab><tab><tab>
# just beeps, ie no matches

calling the directory 'normaldirectoryname' causes the directory to
get a slash appended at the first step, but the files inside then
behave exactly the same as above.

According to _complete_debug the whole array of filenames gets passed
down along the chain, it should be available here for some time:
