Visual block mode is interrupted when typing '>'

[jonsmithers]

To reproduce:

1. Make sure the plugin is active (:imap > should show that > has been mapped)
2. Enter visual-block mode (CTRL-V), and make a selection
3. Enter "visual block insert" mode (by pressing I, c, or A).
4. As soon as you type > in this mode, vim exits visual block mode prematurely.

possibly related issues:

• If you insert a string containing the > character, you have to press undo (u) twice to undo a single insert action. If I want to use the . repeat key to repeat a text insertion containing >, it only inserts the portion of the string AFTER the > character.
• I'm unable to properly insert > while in vim-visual-multi's multiple cursor mode
