Thanks Corona688, I had already tried that and found that it would not work because eval attempts to execute the string, but the string is not a command, just a bunch of dash options, e.g.:
script: line 4: eval: -a: invalid option
eval: usage: eval [arg ...]


However you did give me an idea which does work (and I think does not have security issues)...
opts="$(eval echo $opts) $*"
So thanks again!

extract_font_range(3alleg4)					  Allegro manual				       extract_font_range(3alleg4)

NAME
extract_font_range - Extracts a range of characters from a font. Allegro game programming library. SYNOPSIS
#include <allegro.h> FONT *extract_font_range(FONT *f, int begin, int end) DESCRIPTION
This function extracts a character range from a font and returns a new font that contains only the range of characters selected by this function. You can pass -1 for either the lower or upper bound if you want to select all characters from the start or to the end of the font. Example: FONT *myfont; FONT *capitals; FONT *fontcopy; ... /* Create a font of only capital letters */ capitals = extract_font_range(myfont, 'A', 'Z'); /* Create a copy of the font */ fontcopy = extract_font_range(myfont, -1, -1); ... destroy_font(capitals); destroy_font(fontcopy); RETURN VALUE
Returns a pointer to the new font or NULL on error. Remember that you are responsible for destroying the font when you are finished with it to avoid memory leaks. SEE ALSO
