if you're editing a file with some uses of these deprecated functions, replace their usages with appropriate references to this variable
pass -Wno-deprecated-declarations to ignore these warnings during build
this will mean all users upgrading from e18 to e19 get the new preview
pager. thoose wanting the older plain pager can switch ti pager_plain.
anyon using git will find pager16 remove (or if still installed not
updated) so switch back to pager from pager16. :)
