Improve consistency of the substitution command further. When the opening square bracket ('[') is abused as the delimiter, the regular expression contains a bracket expression, and the bracket expression contains another opening square bracket (sick! - i mean, sic!), then do not require escaping that innermost bracket and treat a preceding backslash as a literal backslash character, in accordance with POSIX: $ printf 'x[x\\x\n' | sed 's[\[[][R[g' xRx\x $ printf 'x[x\\x\n' | sed 's[\[\[][R[g' xRxRx While here, also make the implementation more readable and insert some comments. Joint work with martijn@ (started during g2k18) and OK martijn@.
