* patch(1): Exit successfully if we're fed a 0-length patchKyle Evans2019-03-011-0/+1
| | | | | | | | | | | | | | | | This change is made in the name of GNU patch compatibility. If GNU patch is fed a zero-length patch, it will exit successfully with no output. This is used in at least one port to date (comms/wsjtx), and we break on this usage. It seems unlikely that anyone relies on patch(1) calling their completely empty patch garbage and failing, and GNU compatibility is a plus if it helps with porting, so make the switch.

| | | | | | | | | | | | | | | | Introduce strtolinenum to properly check line numbers while parsing: no signs, no spaces, just digits, 0 <= x <= LONG_MAX Properly validate line ranges supplied in diff file to prevent overflows. Also fixes an out of boundary memory access because the resulting values are used as array indices.
