replace <<EOF type constructs with multi-line echo

This compensates for an selinux bug reported on #gitolite by John Hawley
(warthog9).  sh/bash uses a tempfile to do this, which in turn causes
some problems in selinux; I really don't [need to] know more than that.

*Technically* this is a bug in selinux/policy, and would qualify for an
entry in "nagp"... but:

(1) the changes are small and localised
(2) the problem makes gitolite -- currently -- unusable with selinux,
    and what use is a security program which can't run under selinux
    (regardless of whose fault it is)?

and finally

(3) if I can't break my own rules for one of my most high-profile users
    then what's the point of owning the code?

:-)

Implementation notes: I've only done this for code that is likely/meant
to be used in production

I also slip-streamed in a URL fix (from when I changed all the online
document rendering)
