Log message:
When the last line of the input is empty and the previous line reduced
the line input buffer to a length of one byte, do not write one byte
past the end of the line input buffer. Minimal code to show the bug:
printf ".ds X\n.X\n\n" | MALLOC_OPTIONS=C mandoc
Bug found by bentley@ in the sysutils/rancid par(1) manual page.
