BUG/MEDIUM: variables: some variable name can hide another ones

Browse Source 
The variable are compared only using text, the final '\0' (or the
string length) are not checked. So, the variable name "txn.internal"
matchs other one call "txn.int".

This patch fix this behavior

It must be backported ni 1.6 and 1.7
