Also, since Emacs historically reported a range error when
rounding operations overflowed, do that consistently for all
bignum overflows.
* doc/lispref/errors.texi (Standard Errors):
* doc/lispref/numbers.texi (Integer Basics): Document range errors.
* src/alloc.c (range_error): Rename from integer_overflow.
All uses changed.
* src/floatfns.c (rounding_driver): When the result of a floating
point rounding operation does not fit into a fixnum, put it
into a bignum instead of always signaling an range error.
* test/src/floatfns-tests.el (divide-extreme-sign):
These tests now return the mathematically-correct answer
instead of signaling an error.
(bignum-round): Check that integers round to themselves.
* src/font.c (syms_of_font) <font-weight-table, font-slant-table>
<font-width-table>:
* src/data.c (syms_of_data) <most-positive-fixnum>
<most-negative-fixnum>:
* src/buffer.c (syms_of_buffer) <enable-multibyte-characters>:
Mention in the doc strings that these variables are read-only.
* doc/lispref/variables.texi (Creating Buffer-Local): Document
that making a constant variable buffer-local signals an error.
* doc/lispref/variables.texi (Constant Variables):
* doc/lispref/errors.texi (Standard Errors): More accurate and
up-to-date documentation of which symbols cannot be assigned
values.
The original fix for Bug#6106 switched from signalling `search-failed'
to `user-error'. However, this breaks incremental searching over
multiple nodes because the isearch code doesn't expect a `user-error'.
* src/search.c (syms_of_search): New error, `user-search-failed',
with `user-error' and `search-failed' as parents.
* doc/lispref/errors.texi (Standard Errors): Document it.
* etc/NEWS: Announce it.
* lisp/info.el (Info-search): Use it instead of `user-error' so that
isearch will handle failed searches correctly.
This fixes a recently-introduced bug in delete-directory,
where the code assumes the C locale when determining
whether a file-error corresponds to a missing file (Bug#24714).
* doc/lispref/errors.texi (Standard Errors):
* doc/lispref/files.texi (Changing Files):
* etc/NEWS:
Document this.
* doc/lispref/loading.texi (How Programs Do Loading):
Say "a file-error" rather than "the error file-error" since
it might be a file-missing now.
* lisp/emacs-lisp/bytecomp.el (byte-compile-file):
* lisp/epa-file.el (epa-file--find-file-not-found-function):
(epa-file-insert-file-contents, epa-file-write-region):
* lisp/ffap.el (find-file-at-point, dired-at-point):
* lisp/jka-compr.el (jka-compr-insert-file-contents)
(jka-compr-insert-file-contents):
* lisp/net/ange-ftp.el (ange-ftp-barf-if-not-directory)
(ange-ftp-insert-file-contents, ange-ftp-copy-file-internal):
* lisp/progmodes/etags.el (visit-tags-table):
* lisp/url/url-handlers.el (url-copy-file):
* src/fileio.c (report_file_errno):
Signal file-missing if appropriate.
* lisp/epa-file.el (epa-file-insert-file-contents):
* lisp/jka-compr.el (jka-compr-insert-file-contents):
Don't assume file-error is a leaf in the error hierarchy.
* lisp/files.el (files--force):
* lisp/gnus/nnmaildir.el (nnmaildir--enoent-p):
* lisp/jka-compr.el (jka-compr-insert-file-contents):
Use file-missing to detect whether the file is missing.
* lisp/url/url-handlers.el (url-copy-file):
Signal file-already-exists if appropriate.
* src/fileio.c (syms_of_fileio): Define file-missing.

* doc/lispref/functions.texi (Argument List): Restore the index
entry for 'wrong-number-of-arguments'. (Bug#24222)
* doc/lispref/errors.texi: Fix cross-reference for
'wrong-number-of-arguments'.
Be more systematic about using "@." (not ".") at end of sentence that
ends in a capital letter, and about appending "@:" after non-ends of
sentences that end in a lower case letter followed by "." followed by
whitespace. Omit unnecessary use of "@:" and "@.". Similarly for "?"
and "!". Be more consistent about putting a comma after "i.e." and
"e.g."; this is the typical American style and it's easier to code in
Texinfo.
