10 " 1. On startup, if we were invoked with one file name argument and the file

|
|
|
12 " this file. If there is one then bring it to the foreground and exit.
|
|
|
13 " 2. When a file is edited and a swap file exists for it, try finding that
|
|
|
14 " other Vim and bring it to the foreground. Requires Vim 7, because it
|
|
|
15 " uses the SwapExists autocommand event.
