Support obsolete form of timestamp argument for old POSIX versions. In
summary, when older versions of POSIX are used and the first positional
argument looks like a date and time, then treat it as a timestamp
instead of as a filename. For example, before this commit
_POSIX2_VERSION=199209
POSIXLY_CORRECT=1
touch 01010000 11111111
would create two files, `01010000` and `11111111`. After this commit,
the first argument is interpreted as a date and time (in this case,
midnight on January 1 of the current year) and that date and time are
set on the file named `11111111`.
Fixes uutils#7180.

Good eye, I've updated the test case and the code to match. |
