proxy application arguments should expand tildes
If the user sets things like
ProxyExecutable=/usr/bin/polipo
ProxyExecutableArguments="-c ~/.polipo/config pidFile=~/.polipo/polipo.pid daemonise=true logFile=~/.polipo/polipo.log forbiddenFile=~/.polipo/forbidden"
Vidalia won't expand "~" and the user will get confused. We should consider whether to do basic shell-like expansions ourselves.
Are there other config lines in Vidalia where we should also consider shell-like expansions?
