Fix example in help for :try

[Shane Harper]

The first example in the help for :try is incorrect:

:try | edit too much | finally | echo "cleanup" | endtry

:echo "impossible" " not reached, script terminated above

"impossible" is now output.

It used to work prior to patch 8.0.1189 on Unix; "edit too much" would have caused "E172: Only one file name allowed".

A possible fix is to replace the first line with

                :try | call items("invalid argument") | finally | echo "cleanup" | endtry

[Bram Moolenaar]

A bit shorter:

try | call Unknown() | finally | echomsg "cleanup" | endtry
echomsg "not reached"

This uses "echomsg" so that ":messages" shows the output again.

It actually also didn't work until the recent fix for finding the "|".
