When I send a big mail using smtpmail, I get:

Sending email
Sending email12%
Sending email85%
Sending email87%
Sending email90%
Sending email92%
Sending email95%
Sending email97%
Sending emaildone

SPC is needed between text and percentage, I think.  Is what
should be fixed `progress-reporter-do-update', or should every
program that uses `make-progress-reporter' add SPC to the first
argument?
