[feature request] Whether recursive functions can be highlighted about cpp_etudes HOT 2 CLOSED

@LiuYinCarl

1. do you mean use a special color for callee or caller function in mode 1? for mode 1, in the call chain, all functions except the first one are all callers.
2. please re-try calltree.pl 'recur_func1' '' 1 1 -9, giving a negative depth will make some duplicate recursive patterns fold.
3. it is quite easy to implement this feature, use cpio or cat to concatenate the source files together then compute a fingerprint which can indicates code modifcation.
4. it is a good suggestion.

Yes, I mean if use ./calltree.pl 'recur_func1' '' 1 0 9, I hope all the string recur_func1 in the call tree is marked in a special color, so the users can quickly know which call chains are recursive call chain.
