* cpphash.h (struct lexer_state): Remove line_extension member.
* cpplib.c (dequote_string, do_linemarker): New functions.
(linemarker_dir): New data object.
(DIRECTIVE_TABLE): No longer need to interpret #line in
preprocessed source. Delete obsolete comment about return
values of handlers.
(end_directive, directive_diagnostics, _cpp_handle_directive):
Don't muck with line_extension.
(directive_diagnostics): No need to issue warnings for
linemarkers here.
(_cpp_handle_directive): Issue warnings for linemarkers here,
when appropriate. Dispatch linemarkers to do_linemarker, not
do_line.
(do_line): Code to handle linemarkers split out to do_linemarker.
Convert escape sequences in filename argument, both places.
* cppmacro.c (quote_string): Rename cpp_quote_string and
export. All callers changed.
* cpplib.h (cpp_quote_string): Prototype.
* cppmain.c (print_line): Call cpp_quote_string on to_file
before printing it.
* doc/cpp.texi: Document that escapes are now interpreted in
#line and in linemarkers, and that non-printing characters are
converted to octal escapes when linemarkers are generated.
