When users don't have `HOMEBREW_NO_ANALYTICS` or `HOMEBREW_NO_GITHUB_API` set let's display some analytics data in `brew info`. This should be useful for both maintainers and for users of Homebrew. Note this by default combines all installs across options for a single number; for formulae with lots of options it's a bit overwhelming to print the installs per-option. However, for `HOMEBREW_DEVELOPER`s print the full output. Sample non-developer output: ```console $ brew info wget wget: stable 1.19.5 (bottled), HEAD Internet file retriever https://www.gnu.org/software/wget/ /usr/local/Cellar/wget/1.19.5 (49 files, 3.7MB) * Built from source on 2018-09-03 at 20:46:32 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/wget.rb ==> Dependencies Build: pkg-config ✔ Required: libidn2 ✔, openssl ✔ Optional: pcre ✔, libmetalink ✘, gpgme ✘ ==> Options --with-debug Build with debug support --with-gpgme Build with gpgme support --with-libmetalink Build with libmetalink support --with-pcre Build with pcre support --HEAD Install HEAD version ==> Analytics install: 84638 (30d), 353800 (90d), 1372775 (365d) install_on_request: 77926 (30d), 291305 (90d), 1044898 (365d) build_error: 11 (30d) ``` Sample developer output: ```console $ brew info wget wget: stable 1.19.5 (bottled), HEAD Internet file retriever https://www.gnu.org/software/wget/ /usr/local/Cellar/wget/1.19.5 (49 files, 3.7MB) * Built from source on 2018-09-03 at 20:46:32 From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/wget.rb ==> Dependencies Build: pkg-config ✔ Required: libidn2 ✔, openssl ✔ Optional: pcre ✔, libmetalink ✘, gpgme ✘ ==> Options --with-debug Build with debug support --with-gpgme Build with gpgme support --with-libmetalink Build with libmetalink support --with-pcre Build with pcre support --HEAD Install HEAD version ==> Analytics ==> install (30d) wget: 84516 wget --with-debug: 51 wget --with-libressl: 16 wget --with-pcre: 14 wget --with-pcre --with-libmetalink --with-gpgme: 12 wget --with-debug --with-pcre --with-libmetalink --with-gpgme: 8 wget --HEAD: 3 wget --HEAD --with-debug --with-libmetalink --with-gpgme: 3 wget --with-gpgme: 3 wget --with-libmetalink: 3 wget --with-pcre --with-libmetalink: 3 wget --with-debug --with-pcre: 2 wget --with-libmetalink --with-gpgme: 2 wget --with-pcre --with-gpgme: 2 ==> install (90d) wget: 353131 wget --with-debug: 188 wget --with-pcre: 138 wget --with-pcre --with-libmetalink --with-gpgme: 118 wget --with-libressl: 81 wget --with-debug --with-pcre --with-libmetalink --with-gpgme: 47 wget --with-pcre --with-libmetalink: 31 wget --HEAD: 13 wget --with-pcre --with-gpgme: 12 wget --with-gpgme: 11 wget --with-debug --with-pcre: 10 wget --with-libmetalink: 8 wget --HEAD --with-pcre --with-libmetalink --with-gpgme: 4 wget --with-debug --with-pcre --with-libmetalink: 4 wget --with-libmetalink --with-gpgme: 4 ==> install (365d) wget: 1369530 wget --with-pcre: 810 wget --with-debug: 649 wget --with-pcre --with-libmetalink --with-gpgme: 554 wget --with-libressl: 479 wget --with-debug --with-pcre --with-libmetalink --with-gpgme: 235 wget --with-pcre --with-libmetalink: 184 wget --with-gpgme: 67 wget --with-pcre --with-gpgme: 67 wget --with-debug --with-pcre: 65 wget --HEAD: 54 wget --with-libmetalink: 30 wget --with-libmetalink --with-gpgme: 27 wget --with-debug --with-pcre --with-libmetalink: 24 ==> install_on_request (30d) wget: 77827 wget --with-debug: 48 wget --with-pcre: 12 wget --with-pcre --with-libmetalink --with-gpgme: 11 wget --with-debug --with-pcre --with-libmetalink --with-gpgme: 8 wget --HEAD: 3 wget --HEAD --with-debug --with-libmetalink --with-gpgme: 3 wget --with-gpgme: 3 wget --with-libmetalink: 3 wget --with-debug --with-pcre: 2 wget --with-libmetalink --with-gpgme: 2 wget --with-pcre --with-gpgme: 2 wget --with-pcre --with-libmetalink: 2 ==> install_on_request (90d) wget: 290818 wget --with-debug: 157 wget --with-pcre --with-libmetalink --with-gpgme: 101 wget --with-pcre: 100 wget --with-debug --with-pcre --with-libmetalink --with-gpgme: 42 wget --with-pcre --with-libmetalink: 30 wget --HEAD: 13 wget --with-pcre --with-gpgme: 11 wget --with-gpgme: 10 wget --with-debug --with-pcre: 8 wget --with-libmetalink: 7 wget --HEAD --with-pcre --with-libmetalink --with-gpgme: 4 wget --with-debug --with-pcre --with-libmetalink: 4 ==> install_on_request (365d) wget: 1042845 wget --with-pcre: 504 wget --with-debug: 458 wget --with-pcre --with-libmetalink --with-gpgme: 432 wget --with-debug --with-pcre --with-libmetalink --with-gpgme: 201 wget --with-pcre --with-libmetalink: 158 wget --with-gpgme: 61 wget --HEAD: 54 wget --with-pcre --with-gpgme: 49 wget --with-debug --with-pcre: 47 wget --with-debug --with-pcre --with-libmetalink: 24 wget --with-libressl: 23 wget --with-libmetalink: 22 wget --with-libmetalink --with-gpgme: 20 ==> build_error (30d) wget: 9 wget --HEAD: 1 wget --with-debug: 1 ```
