annotate src/window.c @ 6222:63121fdd093f v7.4.446
updated for version 7.4.446
Problem: In some situations, when setting up an environment to trigger an
autocommand, the environment is not properly restored.
Solution: Check the return value of switch_win() and call restore_win()
always. (Daniel Hahler)
