+ eqn: Fix problem with explicite spacing before unary operator
+
+ * src/preproc/eqn/list.cpp (list_box::compute_metrics): Change
+ item spacing type from BINARY to ORDINARY also when previous
+ type is SUPPRESS_TYPE.
+
+ As reported in
+
+ http://lists.gnu.org/archive/html/groff/2016-04/msg00024.html
+
+ by Douglas McIlroy <[email protected]>
+
+ an implicite space is added between an unary operator and it's
+ operand when an explicite space is put before the unary
+ operator. Unary operators are initially set up as binary.
+ Depending on the preceding element their type can be changed
+ to unary. This did not happen when an explicite space ('~' or
+ '^') had been before that operator.
