wc count field widths now are heuristically adjusted depending
on the input size, if known. If only one count is printed, it
is guaranteed to be printed without leading spaces.
Previously, wc did not align the count fields if
POSIXLY_CORRECT was set, but POSIX did not actually require
this undesirable behavior, so it has been removed.
* doc/coreutils.texi (wc invocation): Likewise.
