The log carries three author strings for me: the current one, an older commit name of "Sahil Kalgutkar" on the same address, and the GitHub noreply address that GitHub stamps on the merge commit it writes when a PR is merged from the web. This maps all three onto one identity for git shortlog, git log and git blame. It changes no commits and rewrites no history, so every SHA and every pull request link stays exactly as it is.

sahilkalgutkar <kalgutkarsahil98@gmail.com>— the current oneSahil Kalgutkar <kalgutkarsahil98@gmail.com>— an older display name on the same addressSahil Kalgutkar <87792369+sahilkalgutkar@users.noreply.github.com>— the address GitHub stamps on the merge commit it writes whenever a PR is merged from the webThe third is not something I set; it is how GitHub attributes server-side merges. In this repo every commit carrying it is a merge commit.
.mailmapmaps all three onto one identity forgit shortlog,git logandgit blame. It changes no commits and rewrites no history, so every SHA and every pull request link stays exactly as it is — which is the reason to do it this way rather than rewriting authors and force-pushing.
