If -Tman is specified and input is -man, echo the preprocessed (`so'

replaced by file) input.  This replaces earlier behaviour of doing
nothing, which I found unexpected (mandoc should always output).

This requires a buffer in read.c that saves the input lines before being
parsed, with a special hook if `so' is invoked.  This buffer is just
flushed to output if -mman is the input.

While mucking around doing this, I also alpha-ordered the mandoc.h
functions.

Ok schwarze@, with no screaming when the polished patch was published.
