Add a new step to the build to generate a safelist of git-config variables which are appropriate to include in the output of git-bugreport. New variables can be added to the safelist by annotating their documentation in Documentation/config with the "annotate" macro, which is a no-op in AsciiDoc and AsciiDoctor. Some configs are private in nature, and can contain remote URLs, passwords, or other sensitive information. In the event that a user doesn't notice their information while reviewing a bugreport, that user may leak their credentials to other individuals, mailing lists, or bug tracking tools inadvertently. Heuristic blocklisting of configuration keys is imperfect and prone to false negatives; given the nature of the information which can be leaked, a safelist is more reliable. However, it's possible that in some situations, an organization may be less concerned with privacy of things like remote URLs and branch names, and more concerned with ease of diagnosis for their support staff. In those cases, it may make more sense for that organization to modify the code to use a blocklist. To that end, we should try to mark configs which are definitely safe, and configs which are definitely unsafe, and leave blank configs which are somewhere in between. To mark a config as safe, add "annotate:bugreport[include]" to the corresponding line in the config documentation; to mark it as unsafe, add "annotate:bugreport[exclude]" instead. Generating bugreport-config-safelist.h at build time by grepping the documentation for this new macro helps us prevent staleness. The macro itself is a no-op and should not alter the appearance of the documentation in either AsciiDoc or AsciiDoctor, confirmable by running: cd Documentation ./doc-diff --asciidoctor HEAD^ HEAD ./doc-diff --asciidoc HEAD^ HEAD Diffing the rendered HTML shows that only inline comments were added, which shouldn't be a problem. Additionally, add annotations to the sendemail config documentation in order to demonstrate a proof of concept.
