New analyses

[Niols]

• [x] Statistics about redirections (functions, simple command, special built-ins, coumpound commands)
• [ ] What happens inside conditions?
• [ ] break in functions
• [ ] pipes (while read ...? what else?)
• [ ] case patterns
• [ ] dpkg-divert on other packages
• [ ] shift in loops
• [ ] function calls with statically known arguments?
• [ ] dot's arguments known statically?
• [ ] local in a compound command, and at toplevel (if ,,, then local x)
• [ ] scripts that still contain $ in words after expansion
• [x] redirection analyser, also find absurd redrections
• [ ] fonctions defined inside fonctions

(to be completed)
