bug in `touch -c'

[TAKAI Kousuke]

Hello,

I have found a bug in `touch' command from fileutils 4.1.8
that `touch -c' wrongly reports an error for non-existent file.
(At least) SUSv2 seems to say `touch -c FILE' should not write any
diagnostic messages when FILE does not exist.

  % touch --version
  touch (fileutils) 4.1.8
  [...]
  % touch --no-create non-existent-file
  touch: setting times of `non-existent-file': No such file or directory
  %

Fileutils-3.16 and 4.0's `touch' appear to behave as SUSv2 says,
but 4.1 and later version have this problem.

Here is a correction I made.

        * src/touch.c (touch): Don't report an error when --no-create
        is in effect and error was ENOENT.

Sorry for my poor English.
