Hello.

I've got a build step where I do a grepping:

```
find gcc/testsuite -name "*.log" | xargs cat | grep -v "Fortran runtime error:" | grep -v "fortran/simplify.c:" | grep -B10 -A10 "runtime error:" || true
 in dir /home/marxin/BIG/buildbot/buildworker/marxinbox-gcc-ubsan/objdir (timeout 1200 secs)

and I set warningPattern=".*runtime error:.*" and I see following hits:
find gcc/testsuite -name "*.log" | xargs cat | grep -v "Fortran runtime error:" | grep -v "fortran/simplify.c:" | grep -B10 -A10 "runtime error:" || true
 argv: b'find gcc/testsuite -name "*.log" | xargs cat | grep -v "Fortran runtime error:" | grep -v "fortran/simplify.c:" | grep -B10 -A10 "runtime error:" || true'

Issue is that first 2 lines are from debug output of Buildbot and are not result of the command executed.
Is it an issue?

Thanks,
