(c-collect-line-comments): Require same comment start column.
(c-guess-basic-syntax): Fixes for nesting of and
repeated defun-open's inside extern and namespace clauses. This
is done by passing a relpos to `inextern-lang' and `innamespace'.
Also, the relpos in `defun-open' is no longer always bol. It's
always bol when on the top level, however. Changed cases: 5A.5, 5I, 14A.
(c-forward-token-1, c-backward-token-1): New functions to move by tokens.
c-guess-basic-syntax): Fixes for Java 1.1 array initialization brace lists.
Don't narrow, just make a simple check against the given limit.
(c-collect-line-comments): New function.
(c-literal-limits): New function that finds the start and end pos
of a comment or string surrounding point.
(c-literal-limits-fast): A faster variant of `c-literal-limits'
for newer Emacsen where the state returned from
`parse-partial-sexp' contains the starting pos of the last literal.
(c-parse-state): Use (c-point 'bod) instead of
beginning-of-defun directly.
(c-guess-basic-syntax): Fixed a few byte compiler warnings.
(c-backward-to-start-of-do): Break infloop for
invalid code, e.g. when someone types while (TRUE) { at the top of
a buffer, we shouldn't hang when the { is typed!
(c-backward-to-start-of-if): Ensure never
move forward, not even if point < lim.
(c-search-uplist-for-classkey): When searching up for a class key,
instead of hardcoding the extended search for "extern", use the new
variable c-extra-toplevel-key, which is language dependent. For C++,
this variable includes the keyword "namespace" which will match C++
namespace introducing blocks.
(c-guess-basic-syntax): Support for recognizing C++ namespace
blocks, by elaborating on the mechanism used to find external
language blocks. Searches which hardcoded "extern" now use
c-extra-toplevel-key, a language dependent variable. Case clauses
that were modified: CASE 5A.1, CASE 5A.4, CASE 5F, CASE 5I, CASE
14A.
CASE 3: we can now determine whether we're at the beginning of a
cpp macro definition, or inside the middle of one. Set syntax to
'cpp-macro in the former case, 'cpp-macro-cont in the latter. In
both cases, the relpos is the beginning of the macro.
(c-forward-syntactic-ws): Added code that skips forward over
multi-line cpp macros.
(c-beginning-of-macro): Moved, and made into a defsubst. This
function can now actually find the beginning of a multi-line C
preprocessor macro.
(c-backward-syntactic-ws): Use c-beginning-of-macro to skip backwards
over multi-line macro definitions.
(c-in-literal, c-fast-in-literal): Use c-beginning-of-macro to
find out whether we're in a multi-line macro definition.
(c-fast-in-literal): Function which should be faster than
c-in-literal. In XEmacs, this uses buffer-syntactic-context.
CASE 5F: extern-lang-close relpos should be
element 0 of inclass-p, not element 1.
(c-beginning-of-statement-1):
Watch out for keywords which have a
preceding underscore.
error results when buffer contains only a comment and point is at eob.
(c-inside-bracelist-p): Add a test to the enum list test so that enum
in a k&r arg decl doesn't confuse handling of the function body.
on a semi following a close brace.
(c-guess-basic-syntax): CASE 5I: When adding 'inclass syntax, use the
relpos pointing to the class opening brace, unless that hangs on the
right side, in which case, use the start of the class/struct keyword.
