Subject: [PATCH] Low confidence for 2-character environment variables (#1831)

These can be automatically generated by the Google Closure Compiler
(which will, if configured, replace global variables with auto-generated
ones such as aa, ab, ac et cetera.) Hence, they are a less reliable
indication that a library which would also set said variable is present.
