        src/bin/sh: sh.1

Log Message:
Correct an incorrectly quoted (unquoted, but should be) example used in
the "local" built-in command description (pointed out by mrg@ via uwe@ in
private e-mail).

Add a description to the export command of why this quoting is required,
and then refer to it from local and readonly (explained in export as that
one comes first).

Note that some shells parse export/local/readonly (and often more) as
"declarative" commands, and this quoting isn't needed (provided the
command name is literal and not the result of an expansion) making
X=$Y type args not require quoting, as they often don't in a regular
variable assignment (preceding, or not part of, another command).
POSIX is going to allow, but not require, that behaviour.  We do not
implement it.
