📄 Description

This fixes #717 by capturing the output into a string for later version extraction.

Additionally, it replaces the subshell calls to head and awk with basic
bash read which is 95+ times faster (in my tests, based on 100000
iterations), simpler and safer (no forking that could fail etc).

NOTE: You'll notice I'm not redirecting stderr anymore. Even the oldest
version of curl I could find (4.8 from 2000) still outputs to stdout so I'm
not sure why this is being captured.

Lastly, it also reuses the curl version information previously obtained for the
command_version() function.
