Change the Tabulated List entry at point, setting COL to DESC.
COL is the column number to change, or the name of the column to change.
DESC is the new column descriptor, which is inserted via
`tabulated-list-print-col'.
If CHANGE-ENTRY-DATA is non-nil, modify the underlying entry data
by setting the appropriate slot of the vector originally used to
print this entry. If `tabulated-list-entries' has a list value,
this is the vector stored within it.
