Denny + + Fix complaints about escape sequences. + Discussed starting at + . + * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER): + For a \0 and similar escape sequences meaning the null + character, report an invalid escape sequence instead of an + invalid null character because the latter does not actually + appear in the user's input. + In all escape sequence complaints, don't escape the initial + backslash, and don't quote when the sequence appears at the end + of the complaint line unless there's whitespace that quotearg + won't escape. + Consistently say "invalid" not "unrecognized". + Consistently prefer "empty character literal" over "extra + characters in character literal" warning for invalid escape + sequences; that is, consistently discard those sequences. + * tests/input.at (Bad escapes in literals): New. + +2009-08-19 Akim Demaille + + doc: fixes. + * doc/bison.texinfo: Fix minor Texinfo errors. + +2009-08-19 Akim Demaille + + doc: %initial-action to initialize yylloc. + Reported by Bill Allombert. + * doc/bison.texinfo: Set fill-column to 76. + (Location Type): Document the use of %initial-action to initialize + yylloc. + +2009-08-18 Joel E.
