76 bool added secondary = richloc.add_location_if_nearby (*global_dc,
77 secondary_loc);
78 error_at (&richloc, "main message");

97 Attempt to handle formatting: if INSERTION_POINT is the first thing on
98 its line, and INDENT is sufficiently sane, then add CONTENT on its own
99 line, using the indentation of INDENT.
100 Otherwise, add CONTENT directly before INSERTION_POINT.
101
102 For example, adding "CONTENT;" with the closing brace as the insertion
103 point and using "INDENT;" for indentation:
104
105 if ()
106 {
107 INDENT;
108 }
109
110 would lead to:

115 CONTENT;
116 }
117
118 but adding it to:

122 would lead to:
