So the place in the code where part of your opening marker was included
in the match... was in the match that originally assigned the value to
the variable:

----------------------------------------------

[usak@cl-t090-563cl bin]$ cat ./test.crm
#!/usr/bin/crm
window
input [test.data] (:data:)
match [:data:] (:context:) /[[:print:]]+/
{
match <fromnext> [:context:] (:focus:) /../
output /Next 2 are: :*:focus:\n/
liaf
}
output /\nSource was: \n:*:data:/

[usak@cl-t090-563cl bin]$ ./test.crm
Next 2 are: bc
Next 2 are: cd
Next 2 are: de
Next 2 are: ef
Next 2 are: fg

Source was:
abcdefg

----------------------------------------------

That's probably not a desirable behavior. ;-)

At least it's consistent with different variable creation methods. I
didn't test it exhaustively, but the behavior is the same with "input"
so it is likely to be the same no matter how the variable is created.
