Fix weird behavior of JumpToMatchingBrace in some ill cases (#1966)

It should not return false immediately when no matching brace is found. This makes the jump fails in certain case: `[  )I]` =/=> `[I  )]`.
When there is no brace near the cursor, the last statement is also executed. This may cause problems when chaining commands.
