concat - Join lists together
concat ?arg arg ...?
This command joins each of its arguments together with spaces after
trimming leading and trailing white-space from each of them. If all the
arguments are lists, this has the same effect as concatenating them
into a single list.
It permits any number of arguments;
if no args are supplied, the result is an empty string.
Although concat will concatenate lists, flattening them in the process
(so giving the following interactive session):
% concat a b {c d e} {f {g h}}
a b c d e f {g h}
it will also concatenate things that are not lists, as can be seen from this
session:
% concat " a b {c " d " e} f"
a b {c d e} f
Note also that the concatenation does not remove spaces from the middle of
values, as can be seen here:
% concat "a b c" { d e f }
a b c d e f
(i.e., there are three spaces between each of the a, the b and the
c).
