Revision 1.55, Thu Jan 15 04:26:39 2015 UTC (5 years, 10 months ago) by schwarze
Branch: MAIN
CVS Tags: VERSION_1_13_3
Changes since 1.54: +3 -3 lines

Fatal errors no longer exist.
If a file can be opened, mandoc will produce some output;
at worst, the output may be almost empty.
Simplifies error handling and frees a message type for future use.
