Problem : Exlicit null dereferenced (FORWARD NULL) @ 2859.
Diagnostic : Real issue.
Rationale : Code within `if (!p_bk)` seems to assume `backup` not null
at that point, which may not be true.
Resolution : Don't enter conditional on null `backup`.
FALSE was being used instead of FAIL.
They happen to have the same value, so it works the same.
But from function comment it's clear it uses the OK/FAIL convention.
Problem : Unchecked return value (CHECKED_RETURN) @ 2644.
Diagnostic : Real issue.
Rationale : Other `u_save` invocations are checked, and there's no
reason to think this invocation could not fail.
Resolution : Check and return if failed (other previous checks in the
same function just return, without reporting error, so
we just do the same).
Problem : Unchecked return value (CHECKED_RETURN) @ 8554.
Diagnostic : Real issue.
Rationale : Other invocations of `do_source` are checked and generate
an error message if fail. There seems to be no reason why
this particular instance could not fail the same.
Resolution : Check invocation and generate error message on failure.
Problem : Array access (via field 'y_array') results in a null pointer
dereference @ 4487.
Diagnostic : Real issue.
Rationale : If the array was previously freed and the size of the array
(y_current->y_size) was not updated to zero, the loop @4486
could be entered and a NULL pointer would be dereferenced.
Resolution : Use free_yank_all() to take care of the NULL check and
to free the current yank register.
Adapt #1533 and #1596 to conform to upstream patch
(https://groups.google.com/forum/#!topic/vim_dev/vp0Lwo9f56s).
Problem: Since patch 7.4.232 "1,3s/\n//" joins two lines instead of
three.
(Eliseo Martínez) Issue 287
Solution: Correct the line count. (Christian Brabandt)
Also set the last used search pattern.
- Update the doxygen comments.
- Use more descriptive types.
- Localize variables.
- Find the '\n' with memchr instead of a for loop.
- Remove `if (size)` checks before memmove
since memmove(dst,src,0) is a noop.
- Use memcpy instead since the pointers don't alias.
- Use xmemdupz instead of vim_strnsave.
- xrealloc instead of xmalloc/memcpy.
- Use memcnt/xmemscan/memchrsub.
Problem: getreg() does not distinguish between a NL used for a line
break and a NL used for a NUL character.
Solution: Add another argument to return a list. (ZyX)

By "simple pointer" I mean a pointer that can be freed with a call to `free`
without leaking any member pointer.
This macro does exactly what `ga_clear_strings` does.
