More systematic output width handling by Joerg Sonnenberger:
* save and restore the output width when switching to MANT_LITERAL
* add an argument to ascii_alloc to specify the output width
* set the default output width to 80 minus 2 characters
* OpenBSD local: set the output width to 65 characters for -man
