common: add missing condition while trimming

The idea of introducing epsilon during trimming was to
eliminate the occurrence of short segments whose length
would be zero when higher computational accuracy was used.
By mistake, during the refactor of 8ed4c2f302,
one of the conditions was lost. Fixed.
