Subject: Replace uses of os.path.abspath with abspath_expanduser_unicode where necessary.... 
X-Git-Tag: allmydata-tahoe-1.8.0b2~70
X-Git-Url: https://git.rkrishnan.org/pf/content/en/seg/biz/?a=commitdiff_plain;h=618db4867c68a6f9e8a45f6d3779553e544b1265;p=tahoe-lafs%2Ftahoe-lafs.git

Replace uses of os.path.abspath with abspath_expanduser_unicode where necessary. This makes basedir paths consistently represented as Unicode.
