make text input more user-friendly

[Blizarre]

The use of the default read command will not allow the user to use arrow keys and shorcuts to enter the data when doing a replace or entering any input, which can be frustrating. Besides, backslashed are interpreted and can be mangled.

• Using the "-e" option will trigger the use of the readline library: you can then, as expected in bash, use the arrow keys and all shortcuts to move around the line before pressing enter.
• Using the "-r" option will prevent the interpretation of the "\" and insert them as typed, useful when pasting code:

$ read -r TESTR
Hello \'World\'
$ read TEST
Hello \'World\'
$ echo $TEST
Hello 'World'
$ echo $TESTR
Hello \'World\'

The user group seems to have been removed, so I created this PR directly.

A small detail, yet a valuable contribution. Thank you!

Please note that Gina is the only person who can accept this, and she's been notably absent in the past months / years. So don't be disappointed. People will still see this and may pull it into their respective forks.

@Blizarre and @inkarkat, you can submit the PR at todotxt/todo.txt-cli if you'd like.

Many thanks for the replies, I noticed the project was not very active at the moment, but I had no idea this fork was almost abandoned. I will post the PR to todotxt, thanks @karbassi!

@Blizarre I believe Gina has made an amazing tool for her todo.txt model but has moved on to bigger and better things.

I'll dedicate some time to bringing the community version (@todotxt/todo.txt-cli) up to speed with changes.

@karbassi thanks for stepping up! I love this tool and I look forward to its evolution!
