[PATCH 5/6] Change output "error: " to "Error: " etc

[John Tapsell <johnflux@gmail.com>]

All the error messages starting "Error: " begin with a captial E, except
in one place.  This commit fixes this, making the output look more
consistent.  At the moment a failed push, say, looks like:

Error: cannot lock existing info/refs
error: failed to push some refs to 'some repository'
