Subject: Support private, group, public as values for umask
X-Git-Url: http://git.tremily.us/?p=ikiwiki.git;a=commitdiff_plain;h=3df7d143469d8d659a9a70cae24b71ddcb73f70e

Support private, group, public as values for umask

These are equivalent to octal 077, 027 and 022, but easier to get from
YAML.
