Problem replacing . with - in version specs

[amotl]

Hi there. Thanks a stack for conceiving and maintaining this invaluable tool.

Problem

A while ago, we discovered that this adjustment applied by pyproject-fmt caused problems installing the package. Apparently, while it might be an alias for some package managers, it isn't for others.

Details

Thoughts

Apologies that we are currently not able to come up with a reproducer. If you are interested, please respond correspondingly, so we will take another stab digging it out. Thank you!
