Most "programmers' editors" have an option to use spaces instead of
tabs, and to set the number of spaces to use.
Emacs has commands (look for "tabify" and "untabify" in the online help)
to replace tabs with spaces, and vice-versa with a single keystroke.
Note: Most programmers prefer to use spaces instead of tabs because tab
sizes vary between machines, programs, and even within a single
program. As long as a fixed-width font is used, spaces are always the
same size. This helps a lot when reviewing code written by someone
else, as it ensures that things line up correctly on the reviewer's system.
