column: make more obvious what is default behavior
The man page contains mistakes. The default is to fill columns before
lines:
$ printf 'aaaaaaaaaaaaaaaaaaaaaa\nBBBBBBBBBBBBBBBBBBBBB\nXXXXXXX\nYYYYYYYYYYY\nZZZZZ' > data
$ column --columns 80 < data
aaaaaaaaaaaaaaaaaaaaaa XXXXXXX ZZZZZ
BBBBBBBBBBBBBBBBBBBBB YYYYYYYYYYY
$ column --fillrows --columns 80 < data
aaaaaaaaaaaaaaaaaaaaaa BBBBBBBBBBBBBBBBBBBBB XXXXXXX
YYYYYYYYYYY ZZZZZ
The patch also rename functions in the code to make it more obvious
for code readers.
