annotate src/ui.c @ 6472:22f95a018b13 v7.4.565
updated for version 7.4.565
Problem: Ranges for arguments, buffers, tabs, etc. are not checked to be
valid but limited to the maximum. This can cause the wrong thing
to happen.
Solution: Give an error for an invalid value. (Marcin Szamotulski)
Use windows range for ":wincmd".
