Subject: [PATCH] new error message convention

Add `raise-argument-error', `raise-result-error', `raise-arguments-error',
and `raise-range-error'.

The old convention was designed for reporting on a single (sometimes very
long line). The new convention is

 <name>: <short message>
   <field>: <detail>
   ...

If <detail> is long or itself spans multiple lines, then it may
also use the form

   <field>:
    <detail>

where each line of <detail> is indented by 3 spaces.

Backtrace information is shown as a multi-line "context" field.
