library/io.m:
library/io.nu.nl:
Implement io__read_line_as_string/{3,4}.
Also sneaked in here are some trivial whitespace fixes in some
of the pragma c_code which did not comply with our coding
standards (to do with type casting).
samples/cat.m:
samples/sort.m:
Use io__read_line_as_string.
tests/general/Mmakefile:
tests/general/read_line_as_string.exp:
tests/general/read_line_as_string.m:
Test case for io__read_line_as_string.
NEWS:
Mention the above change.
