Indeed something like this would have to be the main.cf syntax, unless
there are instead two related append operators:
# String append uses ".="
# Can't think of many particularly compelling examples.
# List append uses ",="
export_environment ,= NAME=value
export_environment ,= {NAME = value}
in master.cf we'd similarly have:
-o { export_environment ,= NAME=value }
-o { export_environment ,= { NAME = value } }
Perhaps given that ".= , ..." can largely emulate ",=", the case for the
latter is less compelling, but I find it somewhat appealing.
The more radical solution is to say that string append is simply not
useful enough to support, and that ".=" always adds ", " to a non-empty
extant value.
