Two space indentation is fairly common in C code bases. GNU projects use a kind of hybrid indentation where child statement are indented by two spaces, but if they are compound statements the indent their interior by another two spaces: if (proprietary(program)) roll_on_floor_twitching(stallman); else { calm_down(stallman); make_indent_weirdly(stallman, everyone); } Google’s style guides for various "C likes" also recommend two space tabs. "Use only spaces, and indent 2 spaces at a time." [Google C++ Style Guide, https://google.github.io/styleguide/cppguide.html https://google.github.io/styleguide/cppguide.html] If you've been staring at Linux kernel code for weeks, with its 8 space tabs, and the edit two-space-tab code, it will take getting used to at first. The indentation will seem small. Soon, it will expand in your mind's eye and look large.
