Browse source 
* grub-core/kern/parser.c (grub_parser_split_cmdline): Add
getline_data argument, passed to getline.
* grub-core/kern/rescue_parser.c (grub_rescue_parse_line): Add
getline_data argument, passed to grub_parser_split_cmdline.
* grub-core/script/lexer.c (grub_script_lexer_yywrap): Pass
lexerstate->getline_data to lexerstate->getline.
(grub_script_lexer_init): Add getline_data argument, saved in
lexerstate->getline_data.
* grub-core/script/main.c (grub_normal_parse_line): Add getline_data
argument, passed to grub_script_parse.
* grub-core/script/script.c (grub_script_parse): Add getline_data
argument, passed to grub_script_lexer_init.
* include/grub/parser.h (grub_parser_split_cmdline): Update
prototype.  Update all callers to pass appropriate getline data.
(struct grub_parser.parse_line): Likewise.
(grub_rescue_parse_line): Likewise.
* include/grub/reader.h (grub_reader_getline_t): Add void *
argument.
* include/grub/script_sh.h (struct grub_lexer_param): Add
getline_data member.
(grub_script_parse): Update prototype.  Update all callers to pass
appropriate getline data.
(grub_script_lexer_init): Likewise.
(grub_normal_parse_line): Likewise.

* grub-core/commands/legacycfg.c (legacy_file_getline): Add unused
data argument.
* grub-core/kern/parser.c (grub_parser_execute: getline): Make
static instead of nested.  Rename to ...
(grub_parser_execute_getline): ... this.
* grub-core/kern/rescue_reader.c (grub_rescue_read_line): Add unused
data argument.
* grub-core/normal/main.c (read_config_file: getline): Make static
instead of nested.  Rename to ...
(read_config_file_getline): ... this.
(grub_normal_read_line): Add unused data argument.
* grub-core/script/execute.c (grub_script_execute_sourcecode:
getline): Make static instead of nested.  Rename to ...
(grub_script_execute_sourcecode_getline): ... this.
* util/grub-script-check.c (main: get_config_line): Make static
instead of nested.
