When you assign a new value to a variable, you may use a my_ variables
using $my_ syntax regardless of what type the target variable is. This
is because mutt uses string representations of both and parses it for
the to-be-assigned var.
For example pager_index_lines is a number, and when you do:
set my_foo=$pager_index_lines
my_foo still is a string because pager_index_lines was converted to
string before the assignment was made. And the same vice versa:
set pager_index_lines=$my_foo
parses the string in $my_foo to an integer number.
Any suggestions for a better wording (besides a missing "uses")?
