Junio C Hamano authored"git log -S<string>" is a useful way to find the last commit in the codebase that touched the <string>. As it was designed to be used by a porcelain script to dig the history starting from a block of text that appear in the starting commit, it never had to look for anything but an exact match. When used by an end user who wants to look for the last commit that removed a string (e.g. name of a variable) that he vaguely remembers, however, it is useful to support case insensitive match. When given the "--regexp-ignore-case" (or "-i") option, which originally was designed to affect case sensitivity of the search done in the commit log part, e.g. "log --grep", the matches made with -S/-G pickaxe search is done case insensitively now.
