[PATCH general-docs] improve notes on pushing to Bitbucket

This tweaks some text from my earlier DevGuide patch, in response to
feedback from Henry Thompson (thanks, Henry!).

I'll apply this late next week if nobody objects.

 The next step is to configure any packages that you want to change so
-that they can be pushed back to Bitbucket.  In the @file{.hg/hgrc} for
-each such package, change the https URL to an ssh URL, i.e.,
+that they can be pushed back to Bitbucket.  Two approaches have been
+shown to work: ssh, and https with your Bitbucket login.
+
+For ssh, you will need to register an ssh public key at Bitbucket.  On
+many systems you can generate a key pair using the @command{ssh-keygen}
+command.  You will also need to change the @code{default} line in the
+@file{.hg/hgrc} for each package to
 
 @example
 default=ssh://hg@@bitbucket.org/xemacs/@var{package_name}
 @end example
 
+For https, change the @code{default} line in the
+@file{.hg/hgrc} for each package to
+
+@example
+default=https://@var{login}@@bitbucket.org/xemacs/@var{package_name}
+@end example
