The problem is that checkpatch returns non-zero for warnings, so this
interrupts my workflow; this means that many of my "patch testing"
scripts will now "fail" due to the shortened limit.
Unless there are documented error codes for checkpatch -- e.g. {0: fine,
1: warnings, 2: errors, 3+: script-errors }
I could then update my scripts to tolerate warnings, but this still
seems like a pain to me.
