This is great. I especially like the distinction between [01:20] and [1:20].

The zsh shell has a brace expansion function, so you can write this in zsh: 

echo f-{fred,barney,vilma}/h{08..22}.t

[download]
which prints 
f-fred/h08.t f-fred/h09.t f-fred/h10.t f-fred/h11.t f-fred/h12.t f-fre
+d/h13.t f-fred/h14.t f-fred/h15.t f-fred/h16.t f-fred/h17.t f-fred/h1
+8.t f-fred/h19.t f-fred/h20.t f-fred/h21.t f-fred/h22.t f-barney/h08.
+t f-barney/h09.t f-barney/h10.t f-barney/h11.t f-barney/h12.t f-barne
+y/h13.t f-barney/h14.t f-barney/h15.t f-barney/h16.t f-barney/h17.t f
+-barney/h18.t f-barney/h19.t f-barney/h20.t f-barney/h21.t f-barney/h
+22.t f-vilma/h08.t f-vilma/h09.t f-vilma/h10.t f-vilma/h11.t f-vilma/
+h12.t f-vilma/h13.t f-vilma/h14.t f-vilma/h15.t f-vilma/h16.t f-vilma
+/h17.t f-vilma/h18.t f-vilma/h19.t f-vilma/h20.t f-vilma/h21.t f-vilm
+a/h22.t

Zsh makes the distinction between {08..22} and {8..22}. Bash 3.0 has cloned this numeric brace expansion feature too (it had non-numeric brace expansion originally), but it expands {08..11} as 8 9 10 11. (Brace expansion with multiple braces sometimes expand in a different order in the shells and your program.)

By the way, your program does not fully expand m[2:5]-{a:t:g:c}, it just prints the four strings m[2:5]-a m[2:5]-t m[2:5]-g m[2:5]-c. Is that intentional?

Also, your program does not seem to be able to expand braces embedded in each other, such as {/usr{:/local}:/var}/lib. Bash expands this to /usr/lib /usr/local/lib /var/lib.
