Operations like gofmt and go-remove-unused-imports delete entire
lines of text. Previously this put them on the kill-ring,
negatively affecting user experience.

Some packages, like popwin.el, change display behaviour based on
the buffer's mode, so we should enable compilation-mode before

godef[1][2] is a third party tool for printing information about
expressions, especially the location of their definition. This can be
used to implement a "jump to definition" function. Unlike
cross-language solutions like ctags, godef does not require an index,
operates on the Go AST instead of symbols and works across packages,
including the standard library.
This patch implements two new public functions: godef-describe (C-c
C-d) and godef-jump (C-d C-j). godef-describe describes the expression
at point, printing its type, and godef-jump jumps to its definition.

Correctly indent the body of functions that have been declared
over multiple lines. See http://play.golang.org/p/MHMwNDbFyf for
an example.
Previously, the body of the function would be indented as deep as
the continuation line of the function declaration. Now it gets
indented as deep as the func keyword.

Instead of relying on gofmt's diff output (which is a unified
diff), we manually invoke diff -n and produce an RCS format diff,
which can easily be parsed in Emacs, with the go--apply-rcs-patch
function.
This fixes undocumented issues with the old implementation such as
skipping over hunks of changes, and it fixes the documented issue
of not being able to handle file names that include whitespace.
It can also apply the patch on a buffer that has no file name
attached at all.
Last but not least, it greatly simplifies the gofmt function
itself.
Fixes#4766.

This CL adds compatibility for GNU Emacs 23 (fixing fontification
issues) and XEmacs >=21.5.32 (fixing a lot of issues). Earlier
versions of XEmacs will not be supported because they do not
support POSIX character classes. Because of that, we also make use
of a lot of functions that were added in 21.5.32.
A known and currently unfixable issue with XEmacs is that go-mode
will not always fontify identifiers that use unicode correctly.
All changes for XEmacs are annotated in the diff.
Note: go--position-bytes is not currently used anywhere, but will
be in a future CL.
Fixes#4927.

This uses the patch output of gofmt (-d option) and applies each
chunk to the buffer, instead of replacing the whole buffer. The
main advantage is that the undo history is kept across gofmt'ings,
so it can really be used as a before-save-hook.

Two fixes for indentation problems:
1. Properly recognize multi-line strings. These start with `, not ".
2. Don't indent a line if the beginning of the line is the end of a multi-line string. This happened for instance when inserting a closing bracket after a multi-line string.

Instead of syntax-tables, an extended go-mode-cs is used for
from a font-lock callback.
Cache invalidation must happen in a before-change-function
because font-lock runs in an after-change-function, potentially
before the cache invalidation takes place.
Performance is reasonable, even with src/pkg/html/entity.go
and test/fixedbugs/bug257.go.

Sometimes during editing, when the buffer is emptied (for example,
as part of a call to M-x gofmt), an error is raised when
remove-text-properties is called. Ensure that these calls use point-max
