#64326: app PortGroup: app.name unable to handle names with spaces

 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.7.1
 Keywords:              |       Port:  pg-app-1.0
------------------------+------------------------
 Similar to ticket #64325, when an {{{app.name}}} is specified with spaces
 in it, the resulting app bundle has curly braces around the name. The
 iterations that I've tried are:

 {{{
 app.name    "AppName With Spaces"
 app.name    "AppName\ With\ Spaces"
 app.name    {AppName With Spaces}
 app.name    AppName\ With\ Spaces}
 }}}

 All of them result in the app bundle being created with a name of
 {{{{AppName With Spaces}.app}}}, with literal curly braces surrounding the
 name, or {{{{AppName\ With\ Spaces}.app}}}, with literal curly braces
 ''and'' backslashes.
