annotate src/os_vms.c @ 5068:6a7ae677d6a1 v7.3.1277
updated for version 7.3.1277
Problem: In diff mode 'cursorline' also draws in the non-active window.
When 'nu' and 'sbr' are set the 'sbr' string is not underlined.
Solution: Only draw the cursor line in the current window. Combine the
'cursorline' and other highlighting attributes. (Christian
Brabandt)
