Subject: Teach magic-folder join to use argv_to_abspath
X-Git-Url: https://git.rkrishnan.org/uri/URI:DIR2:%5B%5E?a=commitdiff_plain;h=7025dd6a264de308ae25a45988e1c9e3479209f7;p=tahoe-lafs%2Ftahoe-lafs.git

Teach magic-folder join to use argv_to_abspath

- also we modify argv_to_abspath to through a usage error
if the name starts with a '-'

- add a test
currently the tests fail
