It would be helpful if Skara bots issued a warning when a PR title starts with a lowercase letter. While a leading lowercase letter is very often unconventional or bad typography, in some cases it is essential; for example:

  * 8331164: createJMHBundle.sh download jars fail when url needed to be redirected
  * 8324776: runtime/os/TestTransparentHugePageUsage.java fails with The usage of THP is not enough
  * 8303689: javac -Xlint could/should report on "dangling" doc comments
  * 8322847: java.lang.classfile.BufWriter should specify @throws for its writeXXX methods
  * 8295111: dpkg appears to have problems resolving symbolically linked native libraries

Hence a warning, not an error.
