When a long list (~4000 lines) is passed to calltip,
lines superimposes each other. Seems, overflowed
"line counter" drops to zero, some new "output cycle"
begins and, as a result, new lines are "printed" over previous ones.
Simple test gives a strange value for this "counter":
the line number 3642 is printed over the first one.
I think, a list passed to calltip can be stripped of stings exceeding first 100-200 since these lines can never be shown in calltip.
This bug is independed of NEdit's version.
