- When 'n' is used as a delimiter escaping 'n' will remain a newline
instead of becoming a 'n' character. This is how POSIX specifies how this
should work. Other implementations tested also do this wrong.
- '[' and maybe other characters are not special during the parsing of the
y command and don't need to be matched or treated special in any way.
- POSIX specifies that a backslash followed by anything other than the
delimiter, 'n', and another backslash, as well as repeating characters in
string1 are unspecified. Since the various implementations handle these
situations in opposing ways choose to error out on them to prevent people
falling into the pitfall of expecting identical behaviour on various
implementations.

While here make corresponding error message for missing read and write file
consistent between commands/flag, and shrink the the code of the w flag of
the s command by making it use the same code as the w command.

the 'w' and 'r' functions and the 'w' flag to the 's' function.
If non of the above is used and input is being read from stdin, we drop
all the way down to stdio!

character in string1 or string2, the two backslash characters shall
be counted as a single literal backslash character"

unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media

also provided as an alias for compatibility with GNU sed.

apparently an extension, but without it you cannot express longer labelled
sed scripts as one-liners. noted by seb@todesplanet.de apr 2002. also
noted by cerille lefevre a bit later. fixed by otto and myself, tested
on tree builds to be careful
