Austin Clements	7443b9649a	Fix missing NUL-terminator in grep Currently, grep read()s into a buffer and then uses the buffer as a string. Since there's no NUL-terminator, this can cause it to falsely identify line breaks and matches from leftover data on earlier lines and, if a line fills up the entire buffer, to read past the end of the buffer. Fix this by NUL-terminating any data returned by read(). Thanks to Keiichi Watanabe for the report.	2015-03-24 20:54:39 -04:00

Fix missing NUL-terminator in grep

Currently, grep read()s into a buffer and then uses the buffer as a
string. Since there's no NUL-terminator, this can cause it to falsely
identify line breaks and matches from leftover data on earlier lines
and, if a line fills up the entire buffer, to read past the end of the
buffer.

Fix this by NUL-terminating any data returned by read().

Thanks to Keiichi Watanabe for the report.
