Determine how text with the "conceal" syntax attribute :syn-conceal is shown:

Value Effect 0 Text is shown normally 1 Each block of concealed text is replaced with one character. If the syntax item does not have a custom replacement character defined (see :syn-cchar) the character defined in 'listchars' is used (default is a space). It is highlighted with the "Conceal" highlight group. 2 Concealed text is completely hidden unless it has a custom replacement character defined (see :syn-cchar). 3 Concealed text is completely hidden.

Note: in the cursor line concealed text is not hidden, so that you can edit and copy the text. This can be changed with the 'concealcursor' option.
