hg-ssh: copy doc string to man page

This corrects a warning from lintian that we're shipping an executable without
a man page. Since there is a doc string in the text, let's use that for the man
page.

+Synopsis
+""""""""
+**hg-ssh** repositories...
+
+Description
+"""""""""""
+**hg-ssh** is a wrapper for ssh access to a limited set of mercurial repos.
+
+To be used in ~/.ssh/authorized_keys with the "command" option, see sshd(8):
+command="hg-ssh path/to/repo1 /path/to/repo2 ~/repo3 ~user/repo4" ssh-dss ...
+(probably together with these other useful options:
+no-port-forwarding,no-X11-forwarding,no-agent-forwarding)
+
+This allows pull/push over ssh from/to the repositories given as arguments.
+
+If all your repositories are subdirectories of a common directory, you can
+allow shorter paths with:
+command="cd path/to/my/repositories && hg-ssh repo1 subdir/repo2"
+
+You can use pattern matching of your normal shell, e.g.:
+command="cd repos && hg-ssh user/thomas/* projects/{mercurial,foo}"
+
+You can also add a --read-only flag to allow read-only access to a key, e.g.:
+command="hg-ssh --read-only repos/\*"
+
+Bugs
+""""
+Probably lots, please post them to the mailing list (see Resources_
+below) when you find them.
