fix: dot-repeat special symbols handling

[archilkarchava]

Due to the way dot-repeat currently works, typing (or pasting) text that contains special strings like or , or < in the Insert mode and then exiting the Insert mode will result in unexpected behavior.

Here are a couple of examples where extension behaves unexpectedly:

"<BS>" example

1. Type (or paste) in insert mode ""
2. Press Enter (adds new line)
3. Press Escape (switches to Normal mode)
4. Press . (dot)

Expected output:

<BS><BS>
<BS

Actual output:

<BS><BS>
<BS

Demo

BS._handling.mp4

<LT><cmd>call VSCodeNotify('workbench.action.files.openFile') command injection example (also works with other commands, as well as with "<<Cmd>" instead of "<LT><Cmd>")

1. Type (or paste) in insert mode "<LT><cmd>call VSCodeNotify('workbench.action.files.openFile')"
2. Press Enter (adds new line character)
3. Press Escape (switches to Normal mode)

Expected output:

\<LT\>\<cmd\>call VSCodeNotify('workbench.action.files.openFile')

Actual output is the same as the expected output, but the workbench.action.files.openFile command gets called

Demo

Cmd._handling.mp4
