3.5.15 `makefile-script' - create makefile script

Usage: (makefile-script text)
This function will take ordinary shell script text and reformat it so that it will work properly inside of a shell script. It does this by:

1. Except for the last line, putting the string, " ; \" on the end of every line that does not end with a backslash.

2. Doubling the dollar sign character, unless it immediately precedes an opening parenthesis or the single character make macros '*', '<', '@', '?' or '%'. Other single character make macros without enclosing parentheses will fail. For shell usage of the "$@", "$?" and "$*" macros, you must enclose them with curly braces, i.e., "${?}".

3. Prefixes every line with a tab, unless the first line already starts with a tab.

4. The newline character on the last line, if present, is suppressed.

This function is intended to be used approximately as follows:

$(TARGET) : $(DEPENDENCIES) <+ (out-push-new) +> ....arbitrary shell script text.... <+ (makefile-script (out-pop #t)) +>

Arguments:
text - the text of the script
