[gs-code-review] Bug 690152, Regression: Input from stdin on OS X

[Alex Cherepanov]

Continue to access the stream while reading a string (sgets()) until the
string is filled, EOF is reached, or an error occurs. Don't return after
first partial read.

Old code did the same thing for 1-byte reads. This handling is now
extended to the reads of any size.

No differences was found in the testing against 'comparefiles' and CET
suite.
