Subject: cvsserver: Actually implement --export-all
X-Git-Tag: v1.5.3-rc0~90^2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=226bccb9ad42441269507a2101b47424d7c9c477;p=git.git

cvsserver: Actually implement --export-all

Embarrassing bug number two in my options patch.

Also enforce that --export-all is only ever used together with an
explicit whitelist. Otherwise people might export every git repository
on the whole system without realising.
