调研方向

Start with ask_for_word_fix in codespell_lib/_codespell.py, where the issue shows the option numbering and selection logic. Decide whether the starting number should be configurable through an environment variable or CLI flag, then check how that choice fits the existing command-line options. Done means displayed choices and the selected correction both respect the configured start number.

描述

As an example,

$ cat broken.txt 
OLL

When there are multiple options with -i 3 or -i 2:

$ codespell -i 3 broken.txt
OLL
 Choose an option (blank for none):  0) ALL 1) OLE 2) OLD 3) OLLY 4) OIL: 0
broken.txt:1: OLL ==> ALL

It starts with 0 since the underlying code is using enumerate

When I am interactively correcting a bunch of misspellings, I have my left hand on the numbers above qwerty (1,2,3,4), and my right hand on enter.

But, whenever I have to enter 0 (which is pretty frequent) I have to move my right hand back and forth to 0 and back to enter.

It would be nice to be able to configure this to start at 1, so my hand positions don't have to change and I can just zone out and focus on the misspellings instead of having to think about where to move my fingers

The following changes (or some different version of this, configured through a CLI flag?) would let that be configurable:

Am willing to make a PR if this is something that is wanted, would just need to know if it should be a CLI flag or something else
