Nice tip! Didn't think of that.
Thanks.

Although it's four functions and not only two. Thus means
two arrays of pointers.

Interesting solution anyway.

I'm not copying-and-pasting anything.

The point is that the function is called _VERY_ often, so the more is optimized, the better.

Thanks for the advice.

NAME
lessecho - expand metacharacters SYNOPSIS
lessecho [-ox] [-cx] [-pn] [-dn] [-mx] [-nn] [-ex] [-a] file ... DESCRIPTION
lessecho is a program that simply echos its arguments on standard output. But any metacharacter in the output is preceded by an "escape" character, which by default is a backslash. OPTIONS
A summary of options is included below. -ex Specifies "x", rather than backslash, to be the escape char for metachars. If x is "-", no escape char is used and arguments con- taining metachars are surrounded by quotes instead. -ox Specifies "x", rather than double-quote, to be the open quote character, which is used if the -e- option is specified. -cx Specifies "x" to be the close quote character. -pn Specifies "n" to be the open quote character, as an integer. -dn Specifies "n" to be the close quote character, as an integer. -mx Specifies "x" to be a metachar. By default, no characters are considered metachars. -nn Specifies "n" to be a metachar, as an integer. -fn Specifies "n" to be the escape char for metachars, as an integer. -a Specifies that all arguments are to be quoted. The default is that only arguments containing metacharacters are quoted SEE ALSO
