[HIG] GError and error alerts

[Gregory Merchan <merchan phys lsu edu>]

GLib has error reporting functions in the GError API. Part of the GError
struct is a message which the API documentation states is a "human-readable
informative error message."

Alerts are supposed to include primary and secondary text. It would be nice
if the GError messages were suitable for one of these, and to know for which.

A string freeze is approaching, but perhaps by 3.0 a review of the GError
messages can be done with error alerts in mind.

Perhaps also, when the HIG is reviewed for code-friendliness, some mention
of GError message formating can be made.


Cheers,
