* radare2-shell-parser: shrink to single-command output when substituing
Before this patch, when substituing arguments the entire input string
was considered, making the process potentially slow if the input was
long. With this patch, substitute_args and parse_args work on a shrinked
version of the input, which includes only the current command.
Not only it improves performance, but it also prevents issues where
other non-related parts of the input string could be replaced during
apply_edits.
* radare2-shell-parser: implement some iter commands
* Add support for number_command and recursive help
* cmd_ignbithints should be set everywhere for consistency
* Save rnum->value before doing a cmd substitution
* Update radare2-shell-parser to fix null deref in html_disable_command
