Subject: install-doc-quick: allow specifying what ref to install
X-Git-Tag: v2.16.0-rc0~18^2
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/65289e9dcdd05f23e871d5aea1c90f217f581f53?hp=--cc

install-doc-quick: allow specifying what ref to install

We allow the builders, who want to install the preformatted manpages
and html documents, to specify where in their filesystem these two
repositories are stored.  Let them also specify which ref (or even a
revision) to grab the preformatted material from.
