2012-07-17 07:45 AEST by Glen Starrett - Currently, the users file only accepts a 'basic' format for email addresses. 
For example:

jdoe:jon.doe@example.com

CVS Mailer also uses the 'users' file, but supports the more extended syntax,
like so:

jdoe:"Jon Doe <jon.doe@example.com>"

This will affect all modules that access the users file (email plugin, bugzilla
plugin, others??).
