the implementation is pretty ... bad. :(
- when a variable expands to something containing $, you could get into
  an infinte loop; you should scan only the part after the last
  substitution
- you have no way to specify a literal $; use backslash escaping
- variable names can also contain lowercase letters, numbers (not as the
  first character), underscores
- the sometimes useful ${} syntax is not supported
- you should not put it into minicli, but krun, i think, probably as an
  additional function; e.g., khotkeys would benefit from it
- the sh syntax "FOO=stuff BAR=morestuff program" should be supported as
  well; sh-style quoting (single and double) including backslash escapes
  should be supported here, too

disclaimer: i know nothing about krun. i hope, the above makes sense
nonetheless. :)

greetings
