People often put diff snippets in changelogs. This causes problems
when one tries to apply a file containing both the changelog and the
diff because patch(1) tries to apply the diff which it found in the
changelog.
Warn once when what seems to be a diff snippet in the changelog exists.

Using "git diff | ./scripts/checkpatch -" does not have an
easy mechanism to see the files and lines actually modified.
Add --showfile to see the file and line specified in the diff.
When --showfile is used without --terse, the second line of each
message output is redundant, so it is removed.

If there are multiple patches/files on the command line,
use a prefix before the patch/file message output like:
--------------
patch/filename
--------------
to make the identifying which messages go with which
file/patch a bit easier to parse.
Move the perl version and false positive messages after
all the files have been scanned so that they are emitted
only once.
Standardize the NOTE: <...> form to always emit a blank
line before the NOTE and always use print << "EOM" style.

Many lines of code extend beyond the maximum line length. Some of these
are possibly justified by use type.
For instance:
structure definitions where comments are added per member like:
struct foo {
type member; /* some long description */
And lines that don't fit the typical logging message style
where a string constant is used like:
SOME_MACRO(args, "Some long string");
Categorize these long line types so that checkpatch can use a command-line
--ignore=<type> option to avoid emitting some long line warnings.
One of the existing checkpatch exclusions allowed kernel-doc argument
documentation to exceed 80 columns because old versions of kernel-doc
required single line documentation. The requirement was removed in 2009
so remove that exclusion.
Add documentation to make the test a bit clearer.

String detection where a source line with a string constant is converted
can either have an X or a space.
Some of the string detection regexes do not allow the space character, but
there is a handy $String variable that does.
Convert the remaining uses of string detection regexes to use the $String
variable to reduce possible false negatives.

checkpatch uses various cues in its input patches and files to discover
the names of user-defined types and modifiers. It then uses that
information when processing expressions to discover potential style
issues.
Unfortunately, in rare cases, this means that checkpatch may give
different results if you run it on several input files in one execution,
or one by one!
The reason is that it may identify a type (or something that looks like a
type) in one file, and then carry this information over when processing a
different file.
For example, drivers/staging/media/bcm2048/radio-bcm2048.c contains this
line (in a macro):
size value;
and drivers/staging/media/davinci_vpfe/vpfe_video.c has this line:
while (size * *nbuffers > vpfe_dev->video_limit)
If checkpatch processes these 2 files in a single command like:
./scripts/checkpatch.pl -f $file1 $file2
the (spurious) "size" type detected in the first file will cause it to flag
the second file for improper use of the pointer dereference operator.
To fix this, store types and modifiers found in a file in separate arrays
from built-in ones, and reset the arrays of types and modifiers found in
files at the beginning of each new source file.

Section headers can be quite long and some are very long and duplicated
for many initial characters.
The current maximum length emitted for a section header is 20 bytes (or
17 bytes then ... when the section header length is > 20).
Change that length to 50 so more of the section is shown.
