Comma and Semicolon functionality for hint_char1

[grezp]

I've created mappings for hint_char1 to behave like f, F, t, and T and it works perfectly. However, there are cases when I need to search the same character again.

Typing f, F, t, and T and then a same char is time consuming when I can just press ; or , to search the same char forwards or backwards. Anyway to achieve this? I couldn't find an elegant solution in the docs.
