Allow < and @ sign in requirements.txt

[overbost]

Every line in requirements is injected in shell, if there are "<" or "<"= sign it break because "<" is special symbol in shell.

Before this line the line should be incorporated in apices like:

"'{r}'".format(r=requirement)

# not works
$ pip install package<=0.5

# works
$ pip install 'package<=0.5'

i temporary solved by adding apices in my requirements

EDIT git repository with specific branch doesn't work, and putting apices doesn't solve. I must use main branch

# not works
git+https://github.com/overbost/myrepo@devbranch

Hello @overbost ,

thank you for pointing this out. Implementing your proposal seems straightforward. But, unfortunately, it does not seem to solve the second issue, which I do not quite understand.

I currently have little availability for this project. Since there is an easy solution (manually wrapping with ''), I'll leave this as so for now. But, I am open to a PR, if someone manages to solve both issues.
