if `first_guess' is zero then main() assumes that locate_hunk has failed
and aborts the patch operation. Instead, make sure to return 1 (the
line number) so that the patch operation can continue.
Issue originally found by Neels Hofmeyr in the regress suite of the diff
implementation for got, where the tests assume that applying a diff with
`patch' and then again with `patch -R' yields back the original file.

When a file is missing, patch(1) will prompt for a filename to try and
patch it. If we're doing a dry-run, we'll output that the patch to the
source file was either ignored/failed. If you ignore the prompt in a
dry-run (i.e. just hit enter), we'll output:
X out of X hunks ignored while patching (null)
Let's improve the aesthetics a bit and just omit the last part if the
prompt was ignored:
X out of X hunks ignored
Unfortunately we can't really test this without expect(1) because both
force and batch mode will use the first best guess, which is wiped out
by the "File to patch:" prompt. We could record the initially derived
bestguess there and use *that*, but given that this is only possible in
an interactive session I think it's fine to just omit the filename
rather than adding a fair amount of complexity (which could also break
other scenarios I haven't considered yet)..

We have a bad habit of duplicating contents of files that are sourced from
/dev/null and applied more than once... take the more sane (in most ways)
GNU route and complain if the file exists and offer reversal options.
This still falls short a little bit as selecting "don't reverse, apply
anyway" will still give you duplicated file contents. There's probably other
issues as well, but awareness is the first step to happiness.

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.

Patches with very little context (-U0 and -U1) could get misapplied if
the file to be patched changes and a hunk is no longer applicable. Matching
with fuzz would be attempted and default to a match when we unexpectedly ran
out of context.
This also affected patches with higher levels of context but had limited
actual context due to the hunk being located near the beginning/end of file.

r325365 caused several ports to fail to patch correctly. Revert it for the

The function savestr allows NULL return values during Plan A patching so in
case of out of memory conditions, Plan B can step in. In many cases, NULL
value is not properly handled, so use xstrdup here (it's outside Plan A/B
patching, which means that even Plan B relies on successful operations).

Other implementations of patch(1), including GNU patch and "svn patch"
have a --dry-run option which does the same as our -C or --check
option.
Add a new alias to make our implementation more compatible.

Patch(1) uses a short int for the line length, which is usually
sufficient for regular diffs, but makes no effort to signal
when there is an overflow.
Change the line length to an unsigned short int to better use
the fact that a length is never negative. The change is loosely
inspired on a related change in DragonFly, but we avoid spending
more memory than necessary.
While here adjust the messages to be clearer on what is happening.

- Tell user what file have failed patch rather than just how
many hunks failed.

fclose() being skipped. Fix this by using boolean "&" and "|" instead of
short-cut operators "&&" and "||".
While here, increment the last part of the version string. The reason is
the fixed output file selection logic in pch.c, which was committed as
r250943, yesterday.

- Remove $DragonFly$ tags as they are using git nowadays and VCS tags will
not help merging.
- Other changes to Copyright headers to make them consistent with other
source code, we intend to fork from this point.
