[petsc-dev] PETSc blame digest (next) 2018-03-05

[Jed Brown]

These warnings are actually attributable to this commit.

commit 153a8027956d231343955b351a2c77b7b409abeb
Author: Barry Smith <bsmith at mcs.anl.gov>
Date:   Fri Mar 2 20:16:55 2018 -0600

    Redefine how the n in PetscStrncat() works to make it more useful and not require tracking the current string size

    Commit-type: feature

should it also be renamed?
