Resolve "LOG_OUTPUT_TRUNC environment variables does not work as expected"
This MR fixes the behavior of the LOG_OUTPUT_TRUNC
variable. First, it corrects a wrong comparison with integer value 0
rather than character value '0'
that prevented truncation to work as expected. Second, it tweaks the code so that an undefined LOG_OUTPUT_TRUNC
does not enable truncation mode.
Closes #185 (closed) #187 (closed)
